MH-Z9041A Methane CH4 Gas Sensor No Need Calibration Long Lifespan
MH-Z9041A Methane CH4 Gas Sensor No Need Calibration Long Lifespan
Description
MH-Z9041A laser CH4 gas sensor (hereinafter referred to as the sensor) is a domestic methane sensor, based on tunable laser gas absorption technology (TDLAS) technology to detect methane gas, internal use of cross-beam light path structure, with excellent gas selectivity, no oxygen dependence, water vapor resistance. Anti-poisoning, long life, etc. Built-in temperature control algorithm, temperature compensation algorithm, to achieve accurate measurement of methane gas; With serial port output interface, easy to use. The sensor is a high performance sensor which combines mature laser gas absorption detection technology with stable optical path design and circuit design.
