Production Description:
MH-712B is a universal type intelligent sensor to detect CO2 in air taking advantages of non-dispersive infrared (NDIR) principle. With good selectivity, no oxygen dependence, stable performance and long lifespan features, MH-712B also has built-in temperature compensation feature. It is a compact and high-performance sensor based on infrared absorption of gas detection technology, micro-machining and sophisticated circuit design.
