TDS meter is used to test the TDS value of water, the conductivity of water, in order to determine who’s purity. At the same time, it has the function of testing water temperature and it can be widely used in the water treatment industry, drinking water industry, family, personal home travel, field operation, and so on. The higher the TDS level in the water, the greater the probability of harmful contaminants that can pose health risks or hinder the absorption of water. The U.S. EPA’s Maximum Contaminant Level of TDS for human consumption is 500 ppm.
