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.

Application

Methane gas alarm for home use

Features

Resistance to water vapor, no poisoning
Response to CH4 gas only, no response to other gases
No need calibration, long lifespan
