Integrated IR (INIR) Gas Sensors

Amphenol SGX Sensortech Integrated IR (INIR) Gas Sensors are designed with an ARM7-core microcontroller to increase reliability and minimize the probability of faults. These user-friendly sensors incorporate the necessary electronics and embedded software to operate from a low voltage DC power supply. Amphenol SGX Sensortech Integrated IR (INIR) Sensors process raw signals to output a linear, temperature compensated signal proportional to the gas concentration applied. The output signal is available in digital and analog forms. These devices offer high resolution up to 10ppm and a detectivity level as low as 100ppm. Typical applications include hazardous areas, mining, automation/control, indoor air quality, and industrial health/safety.
