product description What is TDS and why should I care?We cannot intuitively understand the purity of drinking water.Seemingly transparent water may contain many impuritie. TDS = total dissolved solids,which are inorganic salts and organic matter in the liquid.The lower the TDS level,the purer the water.Conversely,a higher TDS content means that more particles (such as heavy metal ions) are dissolved in the liquid.We are equipped with a backlghit LCD for easy reading.If TDS ≤ 40,the backlight color is green,and if TDS> 40,the backlight color is red. Instructions for use: 1. Remove the pen cover and press the ON key to turn on the tester 2. Place the pen in the solution to be tested,the height of the solution should not exceed 4 cm (from the end of the pen) 3.

[LCD backlight] :Our TDS water meter is equipped with low power backlight technology, which can easily test water at night or in a dark place. It can also be used to distinguish between drinking water and non-drinking water. The red backlight (ppm> 40) reminds the user that the current water quality is not ideal, indicating that this is non-potable water.
[Three-in-one test function]: advanced three-in-one (TDS, EC, temperature) conductivity pen, the tester can not only detect TDS, but also detect EC and temperature in water. The ppm meter range is 0-9990 ppm, and the temperature also supports two reading modes of Celsius and Fahrenheit.
[Simple and convenient operation]: Just turn on the TDS water meter and gently stir the water, and then the stable reading will automatically lock on the LCD within a few seconds; the TDS tester will automatically shut down after not using it for 2 minutes to save battery.
