QB2000N industrial fixed lpg gas leak detector with relay output
QB2000 industrial online combustible gas transmitter alarm system can continusously measure the gas concentration of toxic,combustible and oxygen, it sampling gas by natural diffusion, it also can output RS485 or 4-20mA signal to control pannel, the relay signal be used to activate the fan system.
Features:
♦ Relay output for connecting external device
♦ Modular design is easy to replace and calibrate the sensor
♦ two alarm levels
♦ Important operation needs to verify password
