Co Gas Transmitter 0 - 1% 4-20mA

QB2000N is an industrial wall mount gas detecting transmitter, with4-20 mA or RS485 ModBus RTU output proportional to the gas leakage concentration with electro-chemical or infra red sensor. It monitors gas leakage by natural diffusion. It can be directly connected with PLC 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.
0-1% or 0 -10,0000PPM Co is suitable for where internal combustion engines emit Co in confined spaces such as operating forklifts in warehouses .
Spare parts available, Easy onsite Calibration.
