Zhengzhou Winsen Electronics Technology Co., Ltd. www.winsen-sensor.com MH-440D NDIR Infrared CH4 Sensor (V2.7) 1. Introduction MH-440D infrared gas sensor is a miniature universal intelligent sensor, which adopts NDIR theory to detect concentration of CH4 in air and has good selectivity, stable performance, long life, also is independent of Oxygen. The inside temperature sensor could be used for temperature compensation. This miniature infrared gas sensor is developed by the tight integration of mature infrared absorbing gas detection technology, micro machine workout and superior circuit design. It is convenient in use and also instead of catalytic component directly, widely used in various occasions with flammable and explosion hazard gas. 2.
