Contacting Conductivity Sensors are designed to use in clean water, low conductivity applications below 1000 mS. Most contacting conductivity sensors consist of two metal electrodes that come in direct contact with the process. An electrical field created between the sensor electrodes changes in proprtion to the conductivity of the process.
