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.

Application:

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