Product Description:
MH-741A is a universal type intelligent sensor to detect CH4 gas,taking advantage of non-dispersive infrared (NDIR) principle. With high selectivity, no oxygen dependence, high performance and long lifespan features, MH-741A also has built-in temperature compensation feature. MH-741A is a compact and high-performance sensor based on infrared absorption of gas detection technology, micro-machining and sophisticated circuit design.
