S120 Oil Vapor Sensor

The S120 oil vapor sensor monitors the oil content of compressed air and gases, both permanently or for spot checks when used in conjunction with the S551. To boost accuracy and long term stability, the S120 sensor automatically calibrates at set intervals. Sensor contaminations and sensor lifetime are displayed prominently, and ‘over range’ detection removes the sampling air from the sensor to protect it against contamination.
