Product Description:
MH-440D Electrochemical Infrared Methane Sensor Is Used For HVAC Refrigeration And Indoor Air Quality Monitoring
Features:
MH-440D infrared sensor is a general-purpose intelligent infrared gas sensor (hereinafter referred to as the sensor), using non-dispersive infrared (NDIR) principle to detect hydrocarbon combustible gases in the air, with good selectivity, no oxygen dependence, stable performance, long life; Built-in temperature compensation. The sensor is a compact 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 the presence of flammable, explosive gases in various occasions.
