digital CO2 sensor Amphenol INIR2-CD5% with temperature compensation and high resolution detection
Product Overview
The INIR2-CD5% is a user-friendly digital Gas Sensor designed for reliable carbon dioxide (CO2) detection in industrial and residential environments. Leveraging SGX Sensortechs non-dispersive infrared technology and power-efficient CORTEX microcontrollers, it offers high flexibility and functionality with a linear output proportional to gas concentration. Key advantages include temperature compensation, good accuracy, low voltage DC power supply, and straightforward implementation into end-user systems, making it an ideal solution for gas leakage detection. It is suitable for applications in agriculture, industrial health and safety, and indoor air quality monitoring, and is designed for use in hazardous areas with ATEX and IECEx certifications.
