The Microsense Refrigerant Gas Detector

The Microsense IR is a high quality infrared fixed gas detector for detecting a range of different refrigerant gases. The detector utilises a high quality IR sensor suitable for detection of very low concentrations of refrigerants (less than 10 ppm).

Housed within an IP54 rugged enclosure, the Microsense IR refrigerant gas detector is suitable for use in non-hazardous areas such as plant rooms or hotel and office rooms. It’s integrated algorithm compensates for drift and temperature variations.

The unit offers easy access for installation of field wiring and allows for installation close to floor levels and is compliant with AS/NZS 1677.2.1998 (Refrigerating systems Safety requirements for fixed applications).
