Xiaomi is known for its smartphones, however, the company also manufactures nifty tech and lifestyle gadgets that are useful in daily life. Today we are reviewing one such device called the Mi Water TDS Tester. The TDS in this does not mean Tax Deducted at Source, jokes apart. The TDS stands for Total dissolved solids that are generally found in water. TDS is any salt, mineral or metal that is found in the water. The water that we receive for drinking passes through a filtration process and as a result, may contain dissolved solids. A large number of dissolved solids, more than 1000 mg/L in the water is not suitable for drinking and can be harmful to health.
The Mi Water TDS tester is a thermometer type device which is simple to use. The device is all white in colour and works on 2 x LR44 button cells (not included in the package). The Mi TDS Water tester can detect the TDS quantity of water in the range of 0-9990 ppm. The sensor of the device is anti-rust and anti-corrosive, also the device is IPX6 certified for water resistance. There is a monochrome LCD that displays the TDS reading.
To start using Mi Water TDS tester, insert the two LR44 button cells in the device. Once done, press the TDS button on the device. The device should give a reading of ‘0’. Now insert the device in a glass of water for 3-5 seconds. The TDS reading will change and will be displayed on the LCD
