Infrared carbon dioxide Sensors
MH-710A infrared gas sensor adopt NDIR theory to detect concentration of CH4, good selectivity
Infrared carbon dioxide Sensors
1. Application
MH-710A sensor is a common intelligent sensor in small sized to detect CO2 in air taking
advantages of non-dispersive infrared principle. It has the advantages of good selectivity,
oxygen independence, stable performance and long life. MH-710A is an infrared gas sensor in
small sized combining mature technology for infrared absorption detection and micro-machining,
superior circuit design closely. The sensor can be widely used in detection for fire disaster,
explosive gases.
