- 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).1TDS 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.2Xiaomi 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 deviceExternally, 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.4On 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.3On 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.TestingWe did not check the results in the laboratory, but the values shown by Xiaomi Mi TDS Pen are quite in line with expectations.6thFour types of water were compared from one pipe:HotColdFiltered (reverse osmosis filter)Filtered (reverse osmosis filter), passed through the mineralizerHot 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 ..

- Features & PerformanceThe 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.

- Тестер воды Xiaomi Mi TDS Pen не является универсальным, и не стоит его брать в поход, или по крайней мере полагаться лишь на него при проверке подозрительной воды, поскольку прибор измеряет ограниченный набор веществ. В то же время, для проверки воды из под крана он подходит почти идеально. С его помощью можно не только определить, стоит ли устанавливать дома фильтр, но и проверять его эффективность, а также оценить необходимость замены картриджей. Последнее, кстати, весьма актуально, поскольку фирмы реализующие фильтры советуют менять их раз в полгода, несмотря на ресурс в 5-7 тыс литров, указанный производителем на упаковках, который за этот срок очень сложно израсходовать. Во время тестов использовались картриджи, отслужившие уже 11 месяцев, и при этом, судя по показаниям прибора (20-30 PPM), отнюдь не требующие замены.

- давно хотел заказать, но как-то руки не доходили. теперь благодаря Гирбесту, стал владельцем. как всегда, быстро и без проблем и цена приятнее чем у конкурентов. хотел разобраться, какая по качеству вода из под крана и недавно установленного фильтра для воды(питья и приготовления), стоит ли дальше брать воду из бювета. со своей задачей тестер быстро справился, в качестве Сяоми я не сомневался и давно являюсь их поклонником. выяснилось, что вода с бювета в два раза лучше, чем с фильтра, который судя по всему нужно менять, так как из крана такие же показатели. так что советую! если нужно быстро определить качество воды, то самое оно!

- 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.

- Este Xiaomi TDS pen me ha sorprendido gratamente. La construcción, como siempre es de esperar con Xiaomi, tiene una calidad excelente. Al igual que todos los productos de la serie Mi Home, se presenta con una caja deslizante, de diseño minimalista. Ventajas: -Incluye las pilas ya puestas.-Diseño moderno y minimalista.-Buena calidad de los materiales.Desventajas:-No incluye algún tipo de funda para llevarlo cómodamente sin que se deteriore.-Podría tener bluetooth y sincronizarse con la app mi home o algo parecido para poder guardar las distintas medidas de TDS y así poder llevar un control de distintos lugares.Desventajas son pocas y las que he puesto obviamente incrementarian el precio pero igualmente son ideas.En general lo recomiendo. Muy satisfecho con la compra.
