Description
- 1.The sensor is measuring the electrical conductivity of the water,and computing TDS(Total Dissolved Solids) value in PPM (Parts per Million).2.Completely pure water is an almost perfect insulator,and the conductivity and TDS are near zero.3.Common drinking water has small amounts of salts and minerals which allow the water to conduct electricity.4.The conductivity is very closely linear with the concentration of salts,so this measurement is commonly used to quickly evaluate the purity of water,and especially the effectiveness of RO water treatment.
