STs Series 4-20 mA Conductivity Sensor

The pHionics STs Series Conductivity is a water quality sensor (sonde) designed to pair with a datalogger or RTU for real-time data capture. A narrow diameter allows the STs Series to go places others can’t while the chemical-resistant housing ensures the sensor can stay there for many years. Proprietary electrode technology provides stable measurements to reduce calibration frequency.
