Product Description:
MH-441D Non-dispersive Infrared (NDIR) Principle Methane Gas Sensor Is Used For HVAC Refrigeration And Indoor Air Quality Monitoring
Features:
MH-441D methane gas sensor is a general-purpose intelligent infrared gas sensor (hereinafter referred to as the sensor), using non-dispersive infrared (NDIR) principle to detect methane gas in the air, with good selectivity and no oxygen dependence; The sensor is a compact and high-performance sensor which combines the mature infrared absorption gas detection technology with micro-machining and excellent circuit design. Easy to use, can be directly used to replace catalytic combustion elements, widely used in methane and explosive gas in various occasions.
