CONDUCTIVITY SENSORS
The conductivity sensor is a glass platinum electrode. The principle ofthe meter measurement is to place two discs (conductivity discs) in the sample solution, and a current can be measured by applying a voltage to the two discs. Generally, the voltage is in the form of a sine wave.
Conductivity is determined by the Ohm's formula based on the voltage and current values.
This product is widely used in the conductivity monitoring of water quality treatment,hydrological monitoring, wastewater treatment, swimming pools, fish ponds, and fertilizers, chemicals, biology, and other fields.
