MH-711A NDIR CO2 SENSOR

MH-711A is a universal type intelligent sensor to detect CO2 in air taking advantages of non-dispersive infrared (NDIR) principle. With high selectivity, no oxygen dependence, high performance and long lifespan features, MH-711A also has built-in temperature compensation feature. MH-711A is a compact and high-performance sensor based on infrared absorption of gas detection technology, micro-machining and sophisticated circuit design
