S 120

S 120 Oil vapor sensor

The new oil vapor sensor S 120 monitors oil contents of compressed air and gases permanently or for spot checks when used as portable unit in conjunction with S 551. The simple installation and the outstanding performance makes S 120 the ideal choice when oil vapor contents needs to be measured and monitored.

Oil free compressed air is not an easy task to be achieved. Monitoring is a must in many industries and applications to avoid contaminations in products and risks for health of humans. S 120 makes this monitoring task affordable and reliable.
 
For best accuracy and long term stability, the sensor applies an automatic calibration. Sensor contaminations and sensor life time are monitored and will be indicated to the user. An over range detection will remove the sampling air from the sensor to protect it against contamination.
