QB2000F is a 4-20mA/RS485 Signal Wall-Mounted Fixed Oxygen Sensor O2 Gas Detector Alarm Monitor QB2000F which designed to monitor the gas leakage in the working environment continuously by adopting imported catalytic combustion or electro-chemical gas sensors. The detector has excellent sensibility, quite good accuracy, linearity and receptivity; Big English LCD displays the real-time concentration of the leakage gas. With 2 relay output, once the concentration exceed the preset alarm point (threshold), it will start the acoustic-optical alarm and it can drive the external equipment like exhaust fans; Through 4-20mA signal output, it can be directly connected into the factory DCS system, through RS4845 signal output, it can be connected with factory’s principle computer.


It is widely applied to coal, petroleum, electrochemical, phamaceutical, metallurgy, tabacco, railway, tunnel, etc.
