Brief description
LT-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, with large LCD touch screen, 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.
