S120 Oil Vapor Sensor

The S120 Oil Vapor Sensor monitors oil content of compressed air and gases.

Versatile: permanent or portable measurement for compressed air, N2, or CO2
Accurate: 5% of reading ± 0.003 mg/m3
Detailed: measuring range of 0.001 to 5.000 mg/m3
Integrated: connects to SUTO displays and data loggers for easy monitoring

Description

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.
