Description
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 remind you to take effective actions in time and it could also start the ventilation fan and other equipment to prevent from accident and explosions.
Main Features
1) Advanced MCU control with low power consumption
2) Adjustable low and high alarm level
3) Adjustable calibrating level
4) High concentration protection for combustible gas
5) Self test for the combustible gas sensor
6) Low battery indication
7) Replaceable sensor module
8) Self-adjustment function
9) Visual and audible alarm with vibration
10) STEL and TWA alarming for toxic gases
11) Advanced self-examination and self-renovation function
12) Password management to avoid wrong operation
13) Explosive proof housing
