TDS drinking water tester

TDS water quality tester is a device for testing water. Measures the total amount of all dissolved substances in water (PPM). The measurement is carried out at the level of water conduction, which is why the amount of dissolved salt can be examined. Crystal clean water does not lead the current, and with the increase in the amount of dissolved substances in water appears ions. The more anions and cations, the better the current conduction. Such devices as water tester give the result in PPM, i.e. Mg of substances per ml of water.
