CH4 Gas Sensor
Application:
Hvac refrigeration and indoor air quality monitoringProduct characteristics:
excellent stabilityDescription
The TX721-J1 combustible gas sensor is a general-purpose intelligent infrared gas sensor (hereinafter referred to as the sensor). It utilizes the non-dispersive infrared (NDIR) principle to detect hydrocarbon combustible gases in the air, exhibiting excellent selectivity, no oxygen dependence, stable performance, and long lifespan; it also features built-in temperature compensation. This sensor is a compact, high-performance sensor manufactured by tightly integrating mature infrared absorption gas detection technology with micro-machining and sophisticated circuit design. It is easy to use and can be directly used to replace catalytic combustion elements, making it widely applicable in various situations where combustible and explosive gases are present.
