product description

GDB5 multi-point monitoring gas detection alarm controller is used to detect the content within the lower limit of the flammable gas or liquid vapor explosion in the air. It can be equipped with multiple detection probes to control multiple points at the same time. This system uses a microprocessor as the control unit, and a high-performance catalytic gas sensor as the detection sensor, with high sensitivity and fast response speed. When the concentration of flammable gas in the environment reaches or exceeds the preset alarm value, the controller immediately emits an audible and visual alarm, and drives the exhaust or other peripheral actions to prevent explosions and fire accidents, thereby protecting life and the system can be widely used Carry out safety inspections in factories, oil depots, liquefied gas stations, gas stations, gas stations, paint spray booths, etc. where fire and explosion protection is required.
