The monitoring system for permanent highly precise measurement of the vaporous residual oil content in compressed air.

„Forced Pressure Variation“ for long-term stable measurement results – Auto-calibration
Thanks to the innovative „Forced Pressure Variation“ measuring method, the OIL CHECK 500 generates reference gas internally in different mass concentrations. With the help of this process, which is intellectually protected by CS INSTRUMENTS, components in the measurement signal caused by ageing or contamination, in particular long-term drifts, can be compensated. No wearing parts such as activated carbon filters are necessary for the generation of zero air. The result is a low-maintenance and long-term stable measurement

Service friendly, no downtime
The pre-calibrated sensor unit can be replaced by the customer on site. This eliminates the need to return the entire unit for recalibration.

Process safety
All functions / components are monitored internally. A complete function test report can be printed out via the service software.

On-site calibration
Calibration can be carried out in the field using test gas cylinders. With the service software, a verification report (as-found data) and a calibration report (as-left data) can be generated.
Ideal for mobile measurement
Compact meter, easy sampling and quickly ready for measurement
