Product Description
MH-711A Infrared CO2 Sensor Application
MH-711A 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-711A 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.
Explosion Proof: ExmbⅡCT4
