About conductivity

Conductivity:The conductivity of water is usually used to indicate the purity of water. If the conductivity is high, it means that the content of conductive minerals in water is very high, and the purity of water is very low. If the conductivity is very low, it indicates the minerals that can be ionized in water. Rarely, the purity of water is relatively high. For example, the conductivity of high-purity water is EC=0.1.0us/cm; the conductivity of ordinary drinking water is 1~10 us/c.
