QB2000N fixed hydrocarbon gas detector for toxic gas leakage
QB2000n Fixed Hydrogen Gas Module Monitor Transmitter (0-100%LEL) 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
♦ dust cover offers effectively protection to the sensor
