The Manning AirScan™ iRF9 Gas Sensor is very selective to refrigerants and, because of its stabilized design platform, will provide years of service and maintain the highest level of accuracy and reliability. Manning Systems new SensorCheck™ technology gives the advantage of continually monitoring sensor performance parameters.

The AirScan™ iRF9 is a true "diffusion" design sensor that does not require either pumps or filters and allows all points of detection to be monitored continuously, unlike sample draw systems. The unique features of its internal reference channel compensate for dust particles, source degradation, humidity and temperature fluctuation, food odors, chemical cleaners, etc. This means that years of use will not diminish the performance of Manning Systems AirScan™ iRF9 refrigerant sensor.

A solid high-mass metal bench provides structural and thermal stability, greater immunity to vibration, as well as superior EMI/RFI shielding of the detector and source. Manning Systems patented ATMOS equipped® enclosures allow the AirScan™ iRF9 to automatically adapt to harsh environments, including extreme temperature and humidity changes. The rugged industrial design in the NEMA 4 steel enclosure outputs a linear 4/20 mA signal that can be monitored either by Manning Systems readout/alarm units or a PLC with analog input.
