CH4 gas sensor module Gasboard-2601

CO2CONDIR

Introduction Gasboard-2601 gas filter correlation (GFC) infrared gas sensor is a high-performance gas analysis sensor. The gas sensor bench is based on the principle of NDIR technology and adopts (GFC) infrared absorption technology. By comparing the absorption degree of sample gas and reference gas, the concentration of measured gas is calculated according to the absorption relationship of Lambert-Beer law, and the detection error caused by gas interference is effectively eliminated through the reference gas chamber. The product adopts reliable and stable light source, high-performance detector and precision signal processing circuit, with high measurement accuracy, strong anti-interference ability and long-term stability. Features • Good anti-interference performance based on GFC infrared absorption technology and narrow band filtering structure. • Suitable for ultra-low concentration gas measurement. • Small drift, high stability, less affected by the external environment. • Meet the long-term stability of work with long life light source. • Independent gas detection modular design, rich interface, easy to expand and integrate.
