Description

Oil contamination can occur at various stages of compressed air preparation, creating potential risks for equipment, the environment, and human health. The OIL CHECK 500 control system continuously analyzes compressed air, detects even minimal residual amounts of oil, and ensures air quality compliance with established standards.

OIL CHECK 500 stands out for its ease of use and convenient operation, providing quick and simple handling of the device. Its unique gas sensitivity meets the recommended oil vapor standards according to ISO 8573-5.
