INIR7-R290 Leakage Detection Sensors

Amphenol SGX Sensortech INIR7 R290 Leakage Detection Sensors are user-friendly digital gas sensors based on the Non-Dispersive Infra-Red (NDIR) technology. These sensors feature a 4.5VDC to 30VDC supply voltage range, up to 50ppm high resolution, 200ppm detectivity level, and 120kPa maximum operating pressure. The INIR7 R290 leakage detection sensors include temperature compensation, good accuracy, and simple implementation into the end-user system. Typical applications include residential gas monitoring, heat pumps, refrigeration, chill cabinets, vending machines, cold storage systems, air conditioning, automotive, and R290 leakage detection.
