Flameproof hydrogen sulfide detector for 24-hour online monitoring of industrial toxic gases
This device is compatible with four mainstream detection principles: catalytic combustion, electrochemical, semiconductor, and infrared, covering the full range of industrial gas detection needs. It adapts to different gas detection scenarios, with comprehensive upgrades in accuracy and applicability. The catalytic combustion principle is mainly used for detecting various combustible gases, utilizing the temperature and resistance changes caused by flameless combustion of gas on the catalytic element surface to accurately convert gas concentration, offering good linearity and high stability. The electrochemical principle targets toxic trace gases such as carbon monoxide and hydrogen sulfide, generating corresponding current signals through electrode oxidation-reduction reactions, with strong specificity and high sensitivity at low concentrations. The semiconductor principle is suitable for
