2023 Tshiab tuaj txog GVDA GD156 Handheld Portable Gas Leak Detector Tswb Combustible Flammable Ntuj Methane GD156
Combustible gas detectors yog detectors uas teb rau ib los yog ntau combustible gas concentrations. Muaj ob hom kev ntsuas roj hluav taws xob: hom catalytic thiab infrared optical hom. Lub catalytic combustible gas detector siv qhov kev hloov pauv ntawm cov hlau refractory platinum hlau los ntsuas qhov concentration ntawm cov roj combustible. Thaum cov roj combustible nkag mus rau hauv lub detector, nws ua rau oxidation cov tshuaj tiv thaiv (flameless combustion) nyob rau saum npoo ntawm platinum hlau, thiab lub tshav kub generated tsub kom qhov kub ntawm lub platinum hlau, thiab lub resistivity ntawm platinum hlau hloov. Hom infrared optical siv lub infrared sensor los kuaj xyuas cov pa roj carbon monoxide hauv thaj chaw ib puag ncig los ntawm kev nqus cov ntsiab lus ntawm lub teeb infrared.
