QB2000T is a fixed gas detecting transmitter, with4-20 mA or RS485 ModBus RTU outputproportional to the gas leakage concentration with original imported electro-chemical sensor. It monitors gas leakage by natural diffusion.

It can be directly connected with DCS systems or Central unit.With relay output, once the concentration exceed the preset alarm point(threshold) it will start the acoustic-optical alarm on the central unit and drive the external equipment like exhaust fans.


It has been widely used in petrol, chemistry, metallurgy, artifice, gas transportation, biological medicine and water procession etc.
