The detector, COVAMAT 880 monitors the content of oil vapors in compressed air and other gases. It is available in a stationary version or a portable version for checks on different sites. Its easy connection to the DATAPORT 670 or DATAMON 669 data logger and its exceptional power make the COVAMAT 880 the ideal solution when residual oil contents must be precisely measured and monitored.

It is not easy to guarantee that the compressed air is free of oil. In many industries, particularly food and pharmaceutical industries, surveillance is absolutely necessary to avoid any contamination of products and any risk to human health. The COVAMAT 880 performs this monitoring task reliably and affordably.

For exceptional precision and long-term stability, the sensor is equipped with automatic calibration. Pollution and the lifetime of the sensor are monitored and indicated to the user via status messages. If the maximum admissible residual oil content is accidentally exceeded, the air is diverted by means of a bypass to protect the sensor.
