Manning & IR-F9


The Manning AirScan™ iR sensor responds to refrigerants over the range of 0-3000 ppm and features SensorCheck™ technology that continually monitors sensor performance.The Manning AirScan™ iR infrared sensor is an affordable microprocessor-based sensor that is selective to refrigerants and, because of its stabilized design platform, will provide years of service and will maintain the highest level of accuracy and reliability. This highly versatile sensor features SensorCheck™, a unique technology that continuously monitors sensor performance that enables it to provide worry-free performance throughout the life of the sensor.

A true “diffusion” design sensor, the Manning AirScan™ iR sensor does not require either pumps or filters and allows all points of detection to be monitored perpetually, unlike sample draw systems. The versatile sensor is housed in a high mass metal bench structure that enables thermal stability and freedom from vibration.
