HSJ-8000 multi-point monitoring gas detection alarm controller is used to detect the toxic / flammable gas content in the air. It can take multiple detection probes and control multiple points at the same time. This system uses a microprocessor as the control unit. Performance catalytic gas sensing element is used as a detection sensor, with high sensitivity and fast response speed. Widely used in iron and steel smelting, chlorine plant, acetylene plant, refrigeration workshop, chemical workshop, gas station area, boiler room, hotel kitchen operation room and other places where anti-poisonous, fire-proof and explosion-proof are required.
When the flammable / toxic gas concentration in the environment exceeds the preset alarm value, the controller immediately issues an audible and visual alarm and drives the exhaust air or other peripherals to prevent explosions and fire accidents.
