OIL CHECK 500
The monitoring system for permanent highly precise measurement of the vaporous residual oil content compressed air, nitrogen and gases
To ensure the quality of the compressed air, it is essential to monitor the key parameters precisely.
In addition to the critical pressure dew point, the residual oil content plays an important role.
In numerous production processes, such as in the pharmaceutical, chemical or semiconductor
industries, clean and purified compressed air without any traces of hydrocarbons is of great
importance.
The dispersion mechanism of the residual oil is of particular relevance.
If the oil content exceeds a critical level, the entire system can be contaminated within a very short
time. Due to the low vapor pressure of the molecules forming the oil vapor and their adhesive
properties, it takes a considerable amount of time before the system is completely free of oil residues
again. Cleaning an oil-contaminated pipe network involves considerable effort and high costs.
A breakthrough of residual oil is often only recognized late, usually when quality problems have
already occurred and considerable damage has been caused.
The high quality standards in the industry therefore require continuous and reliable monitoring of the
residual oil content that remains stable over a longer period of time.
This is the only way to detect problems in good time before damage occurs.
The Oil Check 500, with its calibrated measuring range of
1ppb ... 1ppm (corresponds to approx. 0.003 to 3 mg/m³) is a highly sensitive measuring system for
monitoring compressed air systems in order to detect any contamination, including shocks, as early as
technically possible.
The Oil Check 500 is specially designed to ensure the operational safety of your compressed air system between laboratory measurements, to warn you as early as possible if there is a risk of contamination and to avoid false positive alarms.

Ensuring Process Safety with Continuous Oil Vapour Monitoring
In industrial settings, oil contamination in compressed air systems can lead to significant risks, impacting worker safety, environmental integrity, and the longevity of production equipment. To mitigate these dangers, continuous monitoring of oil vapour levels is essential. The METPOINT OCV compact system offers a reliable solution by continuously measuring residual oil vapour concentrations in compressed air, ensuring compliance with relevant industry standards. This advanced monitoring technology not only helps maintain the quality of compressed air but also safeguards your operations from potential hazards associated with oil contamination. By implementing such monitoring systems, businesses can enhance process safety, protect their workforce, and ensure the efficient functioning of their equipment, ultimately leading to improved productivity and reduced operational risks.
Tiny oil particles are an often underestimated risk in the processing of compressed air. Such particles occur in many places in the compressed air system in the form of oil vapour or aerosols and can lead to serious quality problems. The consequences are not only increased scrap or time-consuming rework: even the finest of oil vapour components can contaminate the final product or whole production plants.
Simple and safe operation
The METPOINT OCV compact provides information about the current measurement value (oil vapour in mg/m³), the ISO 8573 oil class as well as the status of the measuring system and its components. In addition, the status of the measuring cell and the reference gas generation (purificator) will be displayed visually. You therefore always have an overview about the measurement values, oil class, system status at all times and know immediately that your compressed air is correct.
