INIR2 Digital Gas Sensors

Amphenol SGX Sensortech INIR2 Digital Gas Sensors are user-friendly digital gas sensors that use non-dispersive infrared technology. These gas sensors are designed to detect refrigeration leakage in industrial and residential environments. The INIR2 gas sensors are developed with the generation of power-efficient cortex® microcontrollers with high flexibility and functionality. The INIR2 gas sensors feature temperature compensation, good accuracy, low-voltage DC power supply, and simple implementation into the end-user system. Typical applications include agriculture, indoor air quality, waste management, environments with varying pressure, automation and control and industrial health and safety.
