Brief introduction:
QB2000F onine ph3 gas monitor transmitter is used to monitor the ph3 gas leakage at site continuously by used of imported electrochemical sensors.
QB2000F online ph3 gas monitor transmitter features large English LCD to monitor the real-time concentration of the ph3 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.
You don't have to install another control panel ,because QB2000F is combi detector and panel.
Pictures as follows shows the combustible gas:
