CS Instruments OIL CHECK 500 | Residual Oil Vapour Analyser for Compressed Air and Gases
The OIL CHECK 500 continuously monitors oil vapour in compressed air and gases, logging trends between laboratory analyses so deviations are caught early. It uses a PID photo-ionisation detector for indicative measurement to ISO 8573-5:2025 and is calibrated at 11 points, three of them within Class 1. Fraunhofer IPM verified a detection limit of 0.0015 mg/m³ at 6 sigma.
Key features
- Forced Pressure Variation checks the zero air before zero adjustment
- Sensor unit replaceable on site
- Low cross-sensitivity to humidity and ethanol
- Optional heater keeps sample gas above 20 °C
- Covers ISO 8573-1 oil classes 0 to 4
