Gravity Industrial Analog Electrical Conductivity Meter Kit for Water Quality Monitoring K1 IP68

Conductivity is the reciprocal of an object's resistivity. It represents a material’s ability to pass a current. In a liquid, conductivity is a measure of a solution’s ability to conduct electricity and can reflect the amount of dissolved or salinity of a water source, so it’s an important parameter in water quality monitoring.
