The Manning AirScan iRF9 refrigerant gas sensor features true diffusion design without pumps or filters, allowing continuous monitoring of all detection points. An internal reference channel compensates for dust, source degradation, humidity, temperature fluctuations, food odors, and chemical cleaners, ensuring years of reliable performance.

SensorCheck technology continuously monitors sensor performance parameters. A solid high-mass metal bench provides structural and thermal stability, vibration immunity, and EMI/RFI shielding. Patented ATMOS-equipped enclosures automatically adapt to harsh environments. NEMA 4 steel enclosure outputs linear 4-20mA signal. Applications include refrigeration systems, supermarkets, food processing, and chemical plants.
