- The instrument measures the so-called TDS (total dissolved solids), or the total mineralization of water, that is, the content of inorganic salts (calcium, magnesium), organic components (ammonium acetate) and heavy metals (chromium, zinc, lead, copper). 1 TDS is measured in PPM, that is, part per million, or particles per million. In other words, 300 ppm means that there are about 300 units of detectable substances in a million water particles. 2 Xiaomi Mi TDS Pen measures TDS between 0 and 1000+ PPM. Remember the meaning of these indicators can always be seen from the image above, but in practice it is useful to remember only that less than 50 is very pure water, 100-300 is ordinary water, usually from a tap, 1000+ - water not suitable for drinking. Appearance and device Externally, the water tester Xiaomi resembles a conventional thermometer, and by the way, it really knows how to measure the water temperature (although it does not show it), in order to take this index into account when determining the mineralization, and to eliminate its effect on the results. 4 On both sides Xiaomi Mi TDS Pen is closed with caps. Under one there are two batteries type LR44 (come with the kit), and under the other - a probe tester made of titanium. 3 On the device itself there is only one on / off button, and to get the results it is enough to lower the probe of the water tester, after which it will instantly show the TDS level. Testing We did not check the results in the laboratory, but the values shown by Xiaomi Mi TDS Pen are quite in line with expectations. 6th Four types of water were compared from one pipe: Hot Cold Filtered (reverse osmosis filter) Filtered (reverse osmosis filter), passed through the mineralizer Hot water, which is also often called technical, predictably showed the worst result in the region of 300+ units. Cold water was slightly cleaner - 240 units. As a device for water treatment, a Ukrainian standard filter was used: a reverse osmosis membrane (manufactured in the USA), and several prefilter filters. The usual filtered water showed a result just above 20 PPM, that is, according to TDS standards it is very clean. If it is passed through the mineralizer in addition, the predicted TDS will increase, but not much. Up to 30 PPM, so that water can still be considered clean ..

- Despite its compact size and the seeming simplicity of its appearance, Xiaomi Mi TDS Water Quality Tester is a device without which those who actually care about their health cannot do. Because this small, tech gadget does a really important and useful job. Namely, it makes a thorough analysis of the composition of drinking water and monitors its quality. Ease of use Verifying that there are no harmful or dangerous impurities in your water is easy with Xiaomi Mi TDS Water Quality Tester. You need to turn on the tester and lower the device into a container with water. Then shake up and wait no more than three seconds. Using the contacts that he made and the built-in temperature compensation sensor, the device immediately starts its work. It with undoubted accuracy determines the composition of water, the impurities dissolved in it, the amount of minerals and salts. And be sure to warn you about exceeding the norm. TDS-tester displays information about their work on a small screen. Screen Xiaomi Mi TDS Water Quality Tester - monochrome, with a fairly clear image. The analysis results appear within one to three seconds. Turning on and off the device by pressing a single button. Does not require recharging Xiaomi Mi works on two miniature batteries for quite a long time. Replacing the batteries is a standard way and does not represent technical complexity. Gadget you can take with you Since Xiaomi Mi TDS Water Quality Tester is mobile, you can take it with you to the country, on a trip or a hike. It will be convenient at home or in the office. And with it, you will know exactly about the quality of the water you drink.

- Features & Performance The Mi TDS Pen can measure the TDS (Total Dissolved Solids) concentration in water. This is not a complete water analysis but TDS is the most common parameter for water testing. The dissolved solids include any salts, minerals, metals, cations or anions dissolved in water, so the lower amount of these solids, the purer the water. The TDS level is measured in parts per million (ppm) or mg/L. The ideal TDS reading for drinking water should be less than 300ppm. The Mi TDS Pen is quite easy to use. It includes two button cells already, so it’s ready to use out of the box. You will just need to take the pen cap off, place the head of the pen under water, then the TDS reading will immediately show up on the display. tested it with the tap water and purified water in my house and the results seem to be accurate. The tap water has the TDS level of 170 ppm while the purified water is much lower at 14 ppm. Therefore, I highly recommend the Mi TDS Pen if you want to check water quality or performance of your water purifying system.

- I was not sure in the quality of the water what we are drinking home, this is why i was ordering the product. The quality of the product is really good, really easy to use, just put the pen to the water what you would like to check and press the button. If you are pressing that button again, device is turning off. Really fast you can check the result. I was comparing the water at home with some mineral waters, and the mineral waters had a little bit better (lower) scores. Unfortunately the box and the small guide is only in Chinese, but luckily on the Gearbest website you can see in English which score is meaning which water quality. The product has a cap, what is saving the pen. You don't need to buy batteries, the pen is containing the 2 batteries, what you can reach if you remove the cap the other side of the pen. Recommended product.

- The Xiaomi Mi TDS Pen water tester is not universal, and you should not take it on a hike, or at least rely on it when testing suspicious water, because the device measures a limited set of substances. At the same time, it fits almost perfectly for testing tap water. With it, you can not only determine whether to install a filter at home, but also check its effectiveness, as well as assess the need to replace cartridges. The latter, by the way, is very important, since the companies implementing the filters advise to change them every six months, despite the resource of 5-7 thousand liters indicated by the manufacturer on the packages, which during this period is very difficult to expend. During the tests, cartridges that have served for 11 months were used, and at the same time, judging by the readings of the device (20-30 PPM), they did not require replacement.

- I have long wanted to order, but somehow my hands did not reach. now thanks to Girbest, became the owner. As always, quickly and without problems and the price is more pleasant than the competition. I wanted to figure out what the quality of the water from the tap and the recently installed filter for water (drinking and preparation), whether to take the water from the pump room. The tester quickly coped with his task, as Xiaomi, I had no doubt and have long been their fan. it turned out that the water from the pump-room is twice as good as from the filter, which apparently needs to be changed, since the same indicators are from the tap. so I advise! if you need to quickly determine the quality of the water, then that is it!

- A handheld water quality checker made by the well known Xiaomi. The TDS tester can be used to verify the total dissolved solids in the water. You can ask why should I buy this device when I know that my drinking water quality is high? Well we don’t have an answer to it but when you are living in a developing country where water has to be treated you can use this device to check the quality of the water. Or when you are travelling and want to know the quality of the water of the Ganges in India or when you a just a curious person of course. Anyway this device works like a charm despite the fact that the standard manual is in Chinese. See more details at: http://www.compareimports.com/blog/xiaomi-water-quality-tester-tds-pen/

- First we have to know that a TDS pen is used to measure the ion concentration, which is not completely equivalent to how clean your water is. If you are worried about chlorine concentration, or the bacteria concentration, then this will be useless to you. The best use of this is to estimate if it's already about time to change the filters of your water cleaning system or, if you want to maintain the ion concentration in your fish tank. Pros: 1. Dummy-proof operation. Just hit the button once, immerse the electrode head in the water, then you can see the measurement. And then, hold the button again to turn it off. 2. Looks solidly built and stylish.
- Suggestion:
- I don't see there is a way to freeze the reading, or store the data.

- This Xiaomi TDS pen has pleasantly surprised me. Construction, as always with Xiaomi, has excellent quality. Like all the products of the Mi Home series, it comes with a sliding box, with a minimalist design. Advantage: -Includes the batteries already placed. -Modern and modern design. -Good quality of materials. Disadvantages: -Does not include some kind of case to carry it comfortably without deteriorating. -I could have bluetooth and synchronize with the app my home or something similar to be able to save the different measures of TDS and thus be able to keep track of different places. Disadvantages are few and those that I have put obviously would increase the price but they are also ideas. In general I recommend it. Very satisfied with the purchase.
