Amphenol SGX Sensortech Integrated IR (INIR) Gas Sensors for R32 & R290

Amphenol SGX Sensortech Integrated IR (INIR) Sensors for R32 and R290 use a microcontroller with an ARM7 core and software that increases reliability while minimizing the probability of faults. These refrigerant gas sensors feature automatic switchover between ranges, high resolution up to 20ppm, detectivity level at 100ppm, and typical low power consumption of <100mW (average). Users can incorporate the infrared sensor into their gas detection instrument to significantly reduce the development time and expertise required during the design and implementation phase. Amphenol SGX Sensortech INIR Sensors for R32 and R290 can be factory calibrated to allow installation without the need for recalibration. Ideal applications include hazardous areas, automation and control, indoor air quality, and industrial health and safety.
