Xiaomi Mi TDS water quality tester. Xiaomi Mi Water Tester Quick Review TDS Pen tds water quality tester

Thanks to the Chinese manufacturer Xiaomi, you can now find out how high-quality water is at home. The company has invented a small device that can test its potability and do it quite well. Moreover, it is already on sale. The name of this miracle device is the Xiaomi Mi TDS Pen Tester Water Quality water tester.

Unboxing

The device is in a small box. white color. The “MI” logo indicates the “brand name” of the packaging.

Inside is a tightly packed device, a small instruction on Chinese and a memo with admissible impurity values. The device is made in the style of a simple writing marker - a square-shaped plastic shell with rounded edges.

On the back of the box there is an instruction for use, in the language of the manufacturer.

What measures

The name Xiaomi TDS or Total Dissolved Solids in English means the total amount of dissolved solid particles. So the device indicates this amount. The unit of measurement is ppm, i.e. the ratio of the number of particles of solids per million particles of liquid.

What is useful

The fact that with the help of a device you can find out the quality of drinking in the kitchen is the first and main purpose. But few people think about the fact that a compact little thing can be taken on a trip. And before sending water to the pot from a local river, it can be tested for suitability. The device is new and equally interesting for both men and women. This means that Xiaomi Pen Tester Water Quality will be a wonderful gift for any occasion.

Functional

According to the developer, the device can detect impurities: calcium and magnesium, as well as zinc, copper, chromium and lead. He will bring out various salts, nitrogen and organic compounds. The stated measurement error is up to two percent. That's what the developer says.

IMPORTANT! All impurities that the device detects are harmful to the body to one degree or another!

On the memo that came with the device, a scale is shown - an excellent assistant in deciphering the received data.

from 0 to 50 ppm the purest drink that has been chemically and thermally cleaned.

from 51 to 100 - after cleaning with coal or taken from mountain sources.

from 101 to 300 units is an acceptable norm.

from 301 to 600 - unpleasant taste due to the high concentration of solids.

from 601 to 1000 - bad taste and critical content of contaminants.

from 1001 and above - you can not use!

How to use

Due to the fact that the rules of application are not provided in Russian, a translator and a special EPA metric are indispensable. But once translated, usage becomes very simple. The algorithm looks like this:

1. Press the button on the LCD screen until 0 ppm lights up.

2. Lower the tester for 5-10 seconds.

3. View the value without taking it out.

IMPORTANT! Due to special protection against liquid ingress into the device, it can be immersed almost completely.

For general development, the indicators of some types of liquid are as follows (ppm):

Bottle 19 liters for a cooler (artesian source) - 78

Aqua Mineral (no gas) - 60

Boiled - 87

Tap water - 320

Melt (plain snow from the street) - 12

Specifications

The tester is powered by a pair of batteries with the number AG13. They come in a set and are placed at the end under a removable cap.

In the center is a small display with a "TDS" button.

At the opposite end of the batteries are sensors. They are covered with a narrow cap. The center contact measures temperature, while the bottom two measure contamination.

Below are numerical values some more features

conclusions

Undoubtedly and undeniably, the Xiaomi water quality tester is a useful thing not only at home, but also on the road. Ease of use, affordable price and compact size - make the device even more attractive and indispensable to use.

Xiaomi Mi TDS pen is an indispensable, easy to operate and very useful device for the systematic monitoring of water quality

Allows you to test your water at home to see if it needs water treatment.

Externally, the device looks like an electronic thermometer. But in addition to temperature, it is able to measure the content of heavy metals in water, organic matter and the salinity of the water as a whole to assess its overall purity.

What is the water quality at home? Test before use!

Initially, xiaomi was engaged in the production of software and smartphones, but quickly realized that all sorts of technology brings a good profit went to create devices for the home. In this review, we'll look at interesting thing– Xiaomi Mi TDS water tester pen. Alas, today this device can be considered a necessity for residents of large cities.

We can't figure out purity drinking water to the naked eye, it would seem in crystal pure water
contains a lot of impurities, the TDS value represents the total content of soluble solids in water, Mi TDS can reflect the water quality to a certain extent. Generally, a lower TDS value indicates less presence of water soluble heavy metal salts, thus cleaner and better water quality. Mi TDS Pen detects water quality and can accurately determine the TDS value of water.

Xiaomi Mi TDS Pen despite its functionality has reasonable price when buying in the online store.

What is Xiaomi Mi TDS Pen?

The water contains substances for measuring the total mineralization of water (TDS - total dissolved solids). This means that thanks to the device, you can find out whether and in what size the water contains:

• heavy metals (lead, chromium, copper, zinc);
• inorganic salts (magnesium, calcium);
• organic compounds (ammonium acetate).
• The total mineralization of water is measured in parts per million or ppm (parts per million).

The World Health Organization (WHO) recommends:

• TDS values ​​below 600 mg/l are generally considered good quality water and recommended to drink
• When the TDS value exceeds 1000 mg/l, there will be a significant change in the taste of drinking water.

To clarify: if Xiaomi Mi TDS pen shows us 250 ppm, it means that millions of water particles contain 250 molecules of unwanted substances. By the way, this is a normal result, relatively safe for the body.

Xiaomi Mi TDS water analyzer pen can measure from 0 to 1000ppm.

There is a special table for decoding the measurement results:

• 0-50 ppm (mg/l) ultrapure water (distilled if possible);
• 50-100 ppm (mg/l) - pure (filtered) water;
• 100-300 ppm (mg / l) - ordinary (tap) water that has undergone initial treatment;
• 300-600 ppm (mg / l) - hard water;
• 600-1000 ppm (mg / l) - hard water is undrinkable, but not poison;
• 1000 ppm (mg/L) is the hazardous liquid value.

Who can use Xiaomi Mi TDS Pen?

It's pretty easy to find practical use water analyzer. The most obvious option is to use a tester to check the quality of filtered water. This is due to xiaomi mi tds pen, you can simply replace the cartridge in the filter jug ​​or reverse osmosis filter.

The thing is, cartridge manufacturers always make recommendations when you need to replace this accessory, but practice (and tester) shows that cartridge sellers care too much about their pockets. Sometimes when using a cartridge, even twice its expiration date, xiaomi mi tds pen shows quite normal ppm water values. At the same time, the recommendations of filter manufacturers are obvious: the more often you replace the cartridge, the more money will fall into their accounts.

You can check ordinary tap water and water from open reservoirs with xiaomi Mi TDS pen. In any case, the manufacturer positions the device as universal. But it is worth considering that if tap water first goes through a certain amount of cleaning and is conditionally considered good for drinking, then water from wells, rivers, lakes and other sources can include a bunch of organic and inorganic substances, bacteria and impurities, which will not be determined in the analyzer. As a result, the tester will show a good result, but the water will be undrinkable. For this reason, it is impossible to consider xiaomi mi tds pen universal tool.

Who else needs a water test tool and why:

• those who live in areas with very hard water, the consumption of which leads to the formation of kidney and bladder stones;
• before pouring water into the iron;
• aquarists add only the right water, purified from hardness salts.

Xiaomi Mi TDS water tester device

The Xiaomi Mi TDS pen resembles an ordinary electronic thermometer, which is closed on both sides of the lid. On one side, lr44 batteries are inserted into the device (they are included in the kit), and on the other side, there are 2 special titanium probes. Titanium provides resistance to corrosion of the instrument and high accuracy.

The analyzer is turned on and off with a single button. For analysis, it is enough to lower the device into a container with water from the side of the probe. The display on the side of the Mi TDS Pen will show the measurement result.

The instrument can be calibrated and is said to be very easy and simple to do. I think that there are still some difficulties - the question remains, where to get the standard for calibration. The only thing that comes to mind is water for injection from a pharmacy, by default, it is ultra-pure, distilled, and therefore well suited for our purposes.

As you know, water temperature always affects the error in determining the mineralization index. To account for this parameter, the analyzer can measure the heating level of the liquid. However, for some reason, manufacturers have decided that users do not need to measure water temperatures, since it is not displayed on the display tester, but simply “take into account”.

So just to keep you informed, here's another example: if you take a hot and cold water from the same faucet in the same apartment, the difference in instrument readings will be about 50-60 ppm. Naturally, hot water will show worse results.

Most likely, the problem is not that xiaomi mi tds pen does not remove errors well due to temperature. There are usually two pipes - one with cold (drinking) water, and the second with hot (as a rule, it is considered technical). In fact, we are talking about liquids with different mineral composition. It is not surprising that the device will show different meanings TDS.

By the way, the water from the reverse osmosis filter shows the content harmful substances about 20-30ppm. After the water pitcher filter, the TDS value is approximately 150-170 ppm (this is normal). Mineral Waters usually show up to 300 ppm this is a fact and minerals, because sometimes you need to use salt, which is good for the body.

Good day dear readers,

This review is dedicated to another water hardness tester (TDS tester) from the well-known company Xiaomi.

Who cares - welcome under the cat

So what is it?

This device measures the hardness of water. There are several but. This is not a laboratory instrument, and the measurement is based on the measurement of water resistance, but it is measured by the TDS device, which stands for Total Dissolved Solids - the total content of dissolved solids. Some call it a "salt meter", because salt fits perfectly into the definition of what the device measures.
The lower the reading of the device, the better, the units change from 0 to 1000, but if the reading is more than 1000 (units per million particles), it is not recommended to drink water.

Let's start

The device comes in a small cardboard box. This is not a grandiose package like caps, but it’s stylish, it’s not for nothing that some people call Xiaomi the Chinese Apple.

The device looks very simple, but it is made with high quality. There is a company logo on the battery cover, and the measuring contacts are under another matte cap.

The device is sold with pre-installed batteries.

Contacts that make the measurements themselves. The manufacturer claims that they are made of titanium (I remind you that they are especially good at oxidation) and there is also thermal compensation. If it is, then it happens "behind the scenes", since the screen shows only the data of this very TDS.

Comparison with handles will give an idea of ​​the size of the device. The screen is small, but the numbers are clearly visible even at an angle. The only button turns the device on and off - a short press turns it on, a long press turns it off.

Some measurements.

It is extremely simple to measure - we dip the contacts into water and almost immediately the measurement result appears on the screen. The results "float", but only by plus or minus 5 units, at least this is how it happens with my device.
- Water in the tap in the office where I work - 480
Water in the filter-cooler in the office (checked on several floors in different coolers) - 320-360
Water in the tap at home (I live in another city, not where the office is, according to Israeli concepts far) - 180
House water after filter Brita - 160
Water after the filter built into the refrigerator (something with coconut fibers ..) - 170
Mineral water Neviot - 220

Conclusions, results

Well, personally, I am very pleased with the device, if only because now I can know when to change filters not only according to the calendar, but also according to the quality of the water itself. Well, over time, I will pick up mineral water with the lowest TDS.

Thank you for your attention.

Hello, today we will talk about the hardness of water measured using a TDS meter or saline meter. This device has already been repeatedly reviewed on the site, but since I live in the foothills of the Caucasus, I had an idea to go camping with this device and measure the hardness of water in a mountain river, mountain stream, forest spring. Therefore, I am going on a real trip and I invite you to a virtual one. Well, I will measure rain, store-bought mineral, bottled non-mineral and tap water. Interesting? Then we read further.

Water hardness - a set of chemical and physical properties of water related to the content of dissolved alkaline earth metal salts in it, mainly calcium and magnesium (the so-called "hardness salts"). (wikipedia)

That is why this device is also called a salt meter. TDS stands for and translates as Total Dissolved Solids - the total content of dissolved solids.
Water hardness is exactly what is responsible for the scale in the kettle and kidney stones.
Let's run a little on the device itself.
On the front there is an on/off button, a reading hold button and a reading display.


At the bottom under the cap are two electrodes that are lowered into the water


On the back there is a clip and a calibration screw

The cap has a built-in battery compartment for two LR44 batteries

The measurement is done like this: Turn on the device, it shows 000, lower the electrodes into the water and look at the value.
The indication is three-segment, if the value is greater than 999, then the x10 sign appears below.
The device measures in US units. ppm measurements, in Russia we have adopted a unit of milligram equivalent per liter, mg-eq / l.
1 meq/l=50.05 ppm
According to Sanitary standards and rules under the number SanPiN 2.1.4.1074-01
the maximum allowable concentration is 7 mg-eq/l. or 350ppm
we will rely on this value, I will also give you such a table, you can also trust it


This instrument is calibrated with a special calibration liquid in which the value of the salt content is known in advance, this instrument is already calibrated by the seller.
The temperature of the water during measurements does not play a special role, since the following property is declared in the characteristics of the device:

Auto temperature compensation

Let's start with room glass measurements.
Drinking tap water

It is also boiled, as you can see, the salt content is slightly lower, boiling softens the water.

Rain water, just went to the balcony and collected water running down from the roof during the rain.

Bottled water from the cooler, it is stated that it is melted, glacial, I do not specifically show the manufacturer.


carbonated mineral water from the store, why I don’t know why such indications this water is extracted from a well, it is enriched with all sorts of elements, maybe for this reason.


Well, now on a hike, our first mountain river

this is what it looks like

Here are the testimonies

In the process of measuring, I threw a bait a couple of times, hoping to catch trout, no luck.

But here is such a plotvichka.

The next one is a spring in the forest. It is believed that this spring has very clean water, many locals collect this water for drinking, and cook only from it. There is even a story that someone took water from it to some kind of scientific research institute, they did an analysis there and said that the water is unique, it can raise the dead, I personally don’t believe it.
I was distracted, so I forgot to take a picture, the readings were 60 ppm, there is this spring at the bottom of the video.
What is characteristic is almost the same as in the river in which I measured earlier, the river flows from the spring about half a kilometer, I have suspicions that this is the same water, only due to filtration through the soil, in the spring it looks crystal clear.
The next place in line is a small mountain stream with a small 2-meter waterfall.

Here are the views on the way to the waterfall

And here is the waterfall

measurements


splashes below, water scatters in all directions, so it was not convenient to take measurements, but nevertheless I measured it and the result was very surprising, I couldn’t take it normally in the photo, but in the end the result was over 1000 ppm, the inscription x10 blinked from the left. Why such high readings in this stream, I do not know, it flows higher from the cave, perhaps for this reason.

In conclusion, I will say that the device is mainly needed in everyday life by the owners of filter systems in order to determine when it is necessary to change the filter element.
