Water pollution meter. Xiaomi TDS tester review – How clean do we drink water? Instructions for using the device for measuring impurities in water

03.03.2020

The problem of clean water exists in almost every home. Someone purchases and installs special filters, while someone just wants to check the condition of the liquid, so they buy a water tester. This device makes it possible to find out whether the water is suitable for domestic use and whether treatment is necessary.

Tester Tasks

Today, a water tester is not such a popular device, since personal filters can also control the quality of water. But it is worth noting that it will not be possible to find an ideal model among these filters, because all of them collect particles of solid matter after long-term use, which can soon get into the water. Most often, people who use cheap filters that do not perform their functions from the first day get hit.

If suddenly the water became suspicious bad smell and color, then a water quality tester will help to find out exactly about its problematicity. It usually appears sewer smell, the taste of chlorine or rotten eggs, but people pay attention to this quite rarely.

Principle of operation

The water tester is designed to measure the amount of heavy particles in a liquid (PPM from 0 to 1000). The higher the value, the more dangerous the water to use. Permissible norm is a PPM from 100 to 300.

Filters can only clean up to a level of 0-50. If the level has reached 600 PPM, then the water will have a strange taste.

Top Models

A water tester will help you check the quality of the filter. Any model provided below will serve its owners for many years without problems. With such devices, you can easily find out the state of drinking water, liquid in the pool or aquarium.

Xiaomi Mi TDS Pen

One of the most famous and respected is the Xiaomi Mi water tester TDS Pen. Despite the fact that initially this production was engaged exclusively in the production of software and smartphones, today under its brand you can find excellent devices for home use.

Xiaomi is a water quality tester that has long become a necessary device for people living not only in major cities but even in the villages. The device determines the content and amount of such substances:

heavy metals - copper, zinc, chromium;
organic components (ammonium acetate);
inorganic salts (calcium).

A water tester, the cost of which reaches 500 rubles, measures everything as accurately as possible. That is, if it shows a value of 250 PPM, then this means that in millions of particles there are exactly 250 particles of unnecessary substances that worsen the condition of the liquid.

Xiaomi's amazing water tester is capable of measuring quantities ranging from 0 to 1000+ PPM. Deciphering the result is not so difficult:

from 0 to 50 - ideally pure water;
from 50 to 100 - a fairly pure liquid;
from 100 to 300 - the usual allowable rate;
from 300 to 600 - hard liquid;
from 600 to 1000 - rather hard water, which is practically undrinkable, although the risk of poisoning is low;
more than 100 PPM - liquid dangerous for use.

Finding a use for a high quality analyzer is fairly easy. Most often it is used to check the quality of water where the filter has already worked. Xiaomi TDS- a water tester that allows its owners to find out in time about the poor performance of cartridges and replace them.

It looks like the most common electronic thermometer, closed on both sides with special caps. On top are the batteries that are included in the kit, and below are two titanium probes.

You can turn the device on or off by pressing a single button. To analyze the liquid, the device must be lowered into a container of water, and then pay attention to the display, which is located on the side and displays the result.

You can also calibrate the device without special efforts. To do this, you can take water intended for injection, sold in pharmacies. It is always ultra-pure and is therefore an excellent reference for calibration.

Before measuring, it should be remembered that the result is affected by the temperature of the liquid. In order to take into account this parameter, the device is able to measure the degree of water heating.

Reviews

Many buyers who regularly use the device already have enough long time, claim that it is almost perfect. There are, of course, some shortcomings in it, but it is absolutely not necessary to take them into account, since they are insignificant.

The device is perfect for those who want to control the quality of the liquid they use, as well as the water in the pool, aquarium, and so on. People speak positively about the good work of the tester. After all, there is no need to press too many buttons and carry out many actions, but just press one button, lower the device into the water and see the exact value.

When there is a need to quickly check drinking water, this device will come to the rescue. Unlike the previous model, this device cannot tell about the quality of the liquid in the pool, but it copes with its main task brilliantly.

Such a tester will be of interest to both adults and children, because it is made in the form of strips. They work on the principle of focus for children, where litmus sticks are required. When the tester is lowered into the water, it turns into a certain color, by which you can understand the state of the liquid.

The tester is designed to detect metals, although it even copes with bacteria and pesticides. The universal product is consumed quickly, so people have to regularly spend money on it. Although in fact the cost is not so high - about $ 21.

Buyer opinions

First of all, people who have used the tester at least once note the convenience and quick results. Unlike other similar products, these strips show the result in just 20-30 seconds, which really pleasantly surprises consumers.

Users claim that thanks to the device they constantly check the condition of their filters and their operation. This makes it possible to always drink only clean water and be completely protected from all sorts of ailments that a person may have due to the use of poor-quality water.

HM Digital TDS-4 Pocket Size TDS

A simple and accurate portable tester, which costs up to sixteen dollars, became a real bestseller literally a day after the release. Despite the fact that most people pay attention to devices famous brands(for example, Xiaomi), the tester from the Digital brand conquered the buyers with its quality of work and affordable price.

His device is capable of measuring levels up to 9990 PPM, since this indicator is already huge in order to recognize low-quality liquid.

What users say

This device, which can be easily put in your pocket and taken with you on trips and hikes, receives positive reviews all the time. It, like both previous models, is easy to use, has an affordable price and does its job perfectly.

People get a tester for the purpose of testing drinking water, although in fact it does a good job with the liquid in the aquarium. Owners of small fish do not want their pets to feel bad, so they are very happy with such an excellent device that makes it possible to enjoy life.

Other models

In addition to those listed above, there are several other good models:

Digital Aid Best Water Quality. The device for $ 16 is distinguished by a maximum 9990 PPM, high performance and a chic shape of the device. In addition, the tester not only determines the new result as accurately as possible, but also remembers several previous ones, which allows you to compare indicators.
HM Digital TDS-EZ Water Quality TDS Tester. Among the best handheld devices, one cannot fail to note the model, the cost of which is $ 13. Far from the most budget device has been on the market for a long time, so buyers can be sure of its quality. The device boasts a good PPM range (0-9990), which allows us to speak only positively about it.
ZeroWater ZT-2 Electronic Water Tester. The $11 device comes in handy in cases where the owner of the filter has forgotten when it needs to be replaced. The measurement range (0-999 PPM) is enough to see the quality of drinking water. The tester works quite well, but it is not intended for daily use.

All of them are also popular and have a huge number of positive feedback. The only problem is that they can not be purchased in every city. Although the quality of their work is really high.

To purify water in everyday life, various purification filters are often used. But in order to make sure that the water is devoid of harmful or excess impurities, it is useful to use a special water tester - this device will help not only test the water for drinking, but also conduct its chemical analysis. Based on the results of such an analysis, showing the level of contamination of the liquid and revealing its composition, you can choose a method of water purification.

Clean drinking water must meet state standards for a number of indicators:

The redox potential of a liquid. This indicator should be in the range from 50 to 100 millivolts. Otherwise, the body will spend a lot of resources in the process of restoring the redox potential.
The pH should be neutral (mark 7.0). In this case, a slight presence of alkali is permissible, but there should be no oxidation at all.
Water hardness should be at an average level. Soft water along with hard water is unacceptable for consumption.
The presence of minerals and salts should not exceed the norm. An excess of these substances harms the kidneys. Their low content is also not useful - in this case, the body will experience a deficiency of the necessary salts and minerals.
The norm for the surface tension of water is 73 dynes / cm. This water is easy for the body to assimilate.
In addition to the above, drinking water should not contain heavy metals, nitrates, nitrites, chlorine and organic compounds of any kind.

Ordinary personal water filters are short-lived - over time, they begin to pass harmful substances and the water acquires an unpleasant odor, most often - hydrogen sulfide, sewage, or chlorine. But not always harmful substances contained in water can be easily detected by smell, then an aquatester comes to the rescue.

This device can be simple, pocket-sized, or a complete kit for complex fluid analysis. If there is a pool in country house or in the country you will need a special set of testers that allow you to check the pool water for the content of chlorine, bromine in it, and also to analyze the pH level.

Working principle and characteristics of the water tester

This portable device has a rather narrow functionality - it calculates the number of heavy particles in the PPM - ("par per million" - "parts per million") from 0 to 1000, and sometimes up to 10,000 (the larger this indicator, the stronger the water pollution). The norm is from 100 to 300 PPM. The measurement result is displayed.

The pocket device is no larger than a thermometer, it is easy to use with a portable filter, especially on the road. It takes only 5 minutes to determine the composition of the water.

A water analysis kit is more complex than a pocket tester. It is a set of reagents that allow, like an indicator, to test water.

Types of aquatester

Monoparametric. The analysis is carried out according to one specific parameter:

pH level;
the amount of salts;
hardness level and so on.

Multiparametric. There are several types of analysis:

chemical,
optic,
electrochemical,
chromatographic,
photochemical.

Testers also differ in the type of analyzed water:

tap water,
ground,
from an artificial pond
technical and waste water.

Aquatesters are also distinguished by the way they are used:

portable;
stationary (installed in water pipes, provide an hourly water status report).

Criteria for choosing an aquatester

Since home filters are not enough to gain firm confidence in the purity and safety of drinking water, it becomes necessary to purchase a tester. What is the best tester to buy? It all depends on what kind of tasks are assigned to this device.

If there are suspicions that the water is hard, it is best to purchase a Salt Meter TDS-3. The device will quickly and accurately calculate the amount of salts in the liquid.

For a comprehensive check of the state of water, it is best to give preference to a universal device that examines the liquid according to the 11 most important parameters - a multi-parameter tester, for example, U-50. Any model from this series is distinguished by high efficiency, convenient control (built-in control unit) and accessible instructions. In addition, multi-parameter water testers of this series are able to memorize the results of the analysis, which can then be easily entered into a personal computer and thus monitor the state of water quality and monitor possible changes in its composition.

If it is necessary to determine the presence of chlorine in water, then for this case it is necessary to purchase a special chlorimeter CL200+. This device has a wide measurement range - from 0.01 to 10 mg / l, which allows you to accurately examine a highly chlorinated liquid. In addition to the main function, the device is able to determine the pH and ORP levels not only in domestic water, but also in any artificial reservoir - an aquarium, pool, boiler, and so on. In addition, the device is economical, since the universal ExTab chemical reagent is used for any analysis. Measurement results are output in digital format.

A special oximeter is designed to detect and calculate the concentration of oxygen (O2) in water. For home use, the Extech DO600+ and AZ8401 models are best. Both devices are a gas analyzer capable of conducting research in an open well of any depth and in a closed hermetic vessel. What is their difference? The first option - Extech DO600 + - is used not only at home, but also in production.

The built-in memory of the device allows you to save the results of the analysis and subsequently compare them with each other. The number of reports that can be saved is 25 pcs. The second option - AZ8401 - is designed to detect and calculate the amount of oxygen not only in ordinary drinking water, but also in any reservoir, including natural (for example, in order to determine whether this reservoir is suitable for fishing, or breeding in it fish). It is worth adding that it is best to measure O2 regularly, since the oxygen concentration is subject to constant changes depending on weather conditions.

To maintain and preserve the health of the body, it is necessary to use and consume only clean water with a normal content of salts and minerals in it. Therefore, an aquatester is one of the most necessary devices in everyday life, because thanks to this compact simple device you can easily determine the condition of drinking water, aquarium water, swimming pools and even natural reservoirs. Based on the results of analysis or regular research and observation, it is possible to identify the problem and take measures aimed at purifying water and protecting the body from exposure to harmful substances.

For what?

We are talking about Xiaomi TDS. The device is curious from several sides at once. Firstly, this is a gadget from Xiaomi, which in itself is interesting for any techno-geek in our country, and not only in our country.

Secondly, each of us, for sure, at least once in his life, but wondered about the quality of the water that he uses for food. Most of us do not drink tap water and rightly so. We do not live in Italy, but in Russia, with communication systems that have already served their purpose. Hence the quality of the water that flows through our pipes. But this is only one side. Some citizens like to travel, find springs and collect water for drinking or pots for cooking. The point, of course, is good, but it will not be superfluous to check the sanitary condition of such water.

And thirdly, the gadget is inexpensive, and in view of the approaching favorite holidays of all of us on February 23 and March 8, it is perfect as a useful gift for a loved one.

Xiaomi TDS price on the official website is 35 Chinese yuan or $5.30, or about 400 rubles. I bought a gadget in one large Chinese online store for $7.25. At first I wanted to post a link to the product, but then I changed my mind. The parcel went to me for two months, so I definitely will not recommend such a store. In private, please.

Theory is important for everyone!

In general, Xiaomi TDS is called so for a reason. The name stands for Total Dissolved Solids and should be understood as the total amount of dissolved (in water) solids. Accordingly, the gadget measures this parameter.

The unit of measure is usually the ratio of milligrams of various solids dissolved in one liter of water (mg/l).

In the case of our device, the unit is used ppm measurements. It stands for the number of particles per million particles of water or in English parts per million (ppm). For ease of understanding, these two units of measurement can be equated. They are really very close to each other.

Functional

Xiaomi TDS is a tiny and stylish device that allows you to determine the exact amount of solids dissolved in one liter of water. Of course, the device may be wrong, but in most cases the error will not exceed two percent of the result. This is exactly what the manufacturer says.

The gadget can recognize the presence of the following substances in water: calcium, magnesium, zinc, chromium, lead, copper, heavy metal ions, ammonium acetate, various salts, organic compounds and so on. All these substances in a certain amount can be harmful to our body.

As a reminder, there is a special scale right on the packaging from under the device, which can be used as a guide when measuring the purity of water.

0 - 50 - crystal clear water (after deionization, microfiltration, distillation, etc.)
50 - 100 - pure water (after carbon filtration, from mountain springs)
101 - 300 - ordinary, heavy water
301 - 600 - high content of various solids, as a rule, drinking such water is already unpleasant
601 - 1000 - critical solids content - bad taste
1000 and above - unsuitable for drinking water

Unfortunately, on the box and in the tiny instructions, all the inscriptions are only on Chinese. It is understandable, because the goods are sold exclusively in China, and it is no secret to anyone that in large cities there big trouble with ecology. First of all, it concerns the purity of the air and drinking water.

I translated the above scale using a Google translator and using a metric developed by the US Health and Safety Organization. environment— Environmental Protection Agency (EPA).

It is very easy to use it. We pressed the button, the value of 0 ppm lit up on the small LCD screen, lowered it into the water, waited 5-10 seconds and that's it. While the device is in the water, it will show its current state, taken out - the value has fallen. As you can see, everything is very accessible.

I tested several types of water that I found at home. And that's what happened.

drinking water from an artesian well, purified, packaged in 19 liter bottles - 78 ppm
Aqua Minerale non-carbonated - 60ppm
the same, but already boiled water - 86 ppm (the kettle was not pre-washed, perhaps additional salts accumulated from there)

tap water - 322 ppm
orange juice - 1030 ppm

But the most interesting indicator was given by melt water - 12 ppm. I scooped snow for her into a glass right in the yard. So think after that, what kind of water you need to use.

Specifications and design

The gadget is powered by two replaceable AG13 button batteries. I'm glad they are already included. The manufacturer was not greedy.

Batteries are hidden at one end of the "handle". In the middle is a small monochrome display, and next to it is a single "TDS" button.

At the bottom end there are sensors covered with a transparent matte cap.

A large contact is responsible for measuring the temperature and calibrating it (not shown), and two smaller “antennae” made of titanium take on the responsibility of measuring solids dissolved in water.

The device is dressed in the form factor of an ordinary stationery marker. The case is entirely plastic, glossy, most likely, over time it will become covered with scratches and become like a devil with horns. But it's beautiful! And it looks great in the box. What else is needed?

model XMTDS01YM
operating temperatures: 0 - 80 degrees
dimensions: 150 x 16 x 16 mm
weight 28 g

Of course, the gadget is resistant to water ingress according to the IPX6 standard. From here it does not matter how deep you dip your "pen" into the liquid. The only thing I have not tried to completely lower the device under water. I don't think anything will happen, but I didn't.

Outcome

Xiaomi TDS tester review the purity of drinking water turned out to be quite short. On the other hand, what else can be said? A simple, useful little thing in the household, which, let's be honest, will be lying around in one of the drawers in your kitchen. I hope I am wrong and will use this device myself from time to time.

At the end helpful information. Perhaps someone does not know. The Department of Rospotrebnadzor is responsible for the quality and safety of drinking water. It is the employees of this department that should conduct appropriate checks in the territory they control. Do not be lazy and go to the website of the local representative office to ask how things are with drinking water in your area. To do this, put the code of your region before the page name and look for the information you need in the site search. For example, 77.rospotrebnadzor.ru is the page of the Moscow Administration.

Water is an integral part of every person's life. We use it every day while cooking, washing dishes, taking a shower or bath. Not always such a liquid entering an apartment or house meets safety standards. It can harm human health or even endanger life. "Wrong" water can in a short period of time disable plumbing, destroy the integrity metal pipes and ruin clothes in the wash.

We have already written an article on this topic. If someone is not familiar with it yet, then be sure to read it. To do this, go to this . In today's article I want to talk about the range Russian market measuring instruments for water quality analysis. We will learn what an aquatester is, what types exist, and consider the most popular models.

Aquatester for measuring the level of PH

A PH water tester is a device that measures the amount of hydrogen in a liquid. These devices at home are able to determine the level of acidity in drinking water. Increased values given parameter harmful to human health. Contribute to the formation of scale, damage to household appliances and plumbing fittings. Exist professional models, intended for laboratory research, however, for home conditions, you can buy a portable aquatester. He will let you do detailed analysis water. The error of such devices is only 0.02%. The price of these models starts from 1000 rubles. For functional samples will have to pay about 5 thousand. To get acquainted with the range of aquatesters for measuring PH, you can follow this link .

ORP tester

The human body is 90% fluid. One of the main factors affecting our general condition and overall health is water quality. Aquatester ORP is a device that determines the redox potential in any liquid. The usefulness of water for a person depends on this parameter. Every time we drink, the body receives an additional portion of acids and alkalis, which contribute to the proper processing of nutrients and stabilize the acid-base environment. The ORP indicator in the human body should vary from -50 to -100 millivolts. The device will measure the specified coefficient. In "good" water, it should not exceed 7.0. The cost of water testers for measuring ORP starts from 2800 rubles for a household appliance. For a professional tester, you will need to pay from 10 to 20 thousand rubles. An approximate range can be found on this link.

TDS tester

TDS tester, saline meter or water hardness meter are versatile devices that can carry out a comprehensive analysis of the liquid. They are great for home use. With the help of such a device, you can find out the hardness of water, electrical conductivity, approximate chemical and mineral composition, as well as determine the presence of impurities and salts. Modern models contain a thermometer and adjust the readings depending on the temperature of the liquid. The advantages of such devices are versatility, compactness, ease of use and display information. Aquatester of this type is able to analyze the liquid within 3 minutes. The cost of models starts from 2500 thousand rubles, and reaches 15 thousand. The range can be viewed at this link .

Outcome

I want to say that the cost of these devices, in my opinion, is not high. If you buy an aquatester once and check the water that flows from the tap, you can be calm about its quality. If the liquid does not meet the established standards, you should think about purchasing filters or cleaning systems.

If you are not familiar with the article about "Cabinet water treatment systems in an apartment or house", you can read it by clicking .

I hope my article today was useful and understandable to you. Write in the comments if you are sure about the quality of your water?! And what do you think, is it worth buying a water tester for the home, if so, which one?
