BH-50 Gas Monitor System is a multipoint controller system. It is used for detecting gas concentration in the air.The system could connect to detectors for different gases in the same time. The system adopts MCU as control unit,excellent gas sensor with high sensitivity and fast response.It will give visual and audible alarm when the gas concentration reach or exceed the presetting alarm level to remindyou to take effective actions in time and it could also start the ventilation fan and other equipment to prevent from accident and explosions.
