S 120 residual oil sensor
The new residual oil 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 residual oil 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.
