INIR2-ME5%
Product Description
Product Overview
The INIR2-ME5% is a user-friendly digital Gas Sensor designed for detecting methane gas leaks in industrial and residential environments. Leveraging SGX Sensortechs non-dispersive infrared technology and power-efficient CORTEX microcontrollers, it offers high flexibility, functionality, and a linear output proportional to gas concentration. Key advantages include temperature compensation, good accuracy, low voltage DC power supply, and simple implementation. It is factory calibrated for up to 5% Methane and designed for use in hazardous areas, holding ATEX and IECEx certifications.
