MH-440D NDIR Infrared CH4 Gas Sensor High Sensitivity High Resolution Fast Response Excellent Stability Long Lifespan
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 instead of catalytic component directly, widely used in various occasions with flammable and explosion hazard gas
Features:
➢ High sensitivity, high resolution, fast response ➢ Output method: UART, analog voltage signal ➢ Temperature compensation, excellent linear output ➢ Excellent stability, long lifespan ➢ Anti-poisons, anti-vapor interference ➢ Can replace catalytic type gas sensor directly.
Applications :
Widely used for HVAC refrigeration, air monitoring indoor, industrial-process control and safety protection, agriculture, and animal husbandry.
