    fixed intelligent H2S detector

    Introductions:
    QB2000N H2S transmitter is a microprocessor based intelligent sensor transmitter. Whichprovides 4-20 mA output andModBus RTU outputproportional to H2S concentrationand has LED(LCD optional) digital display real-time gas concentration. Its RS485 digital signal is for communication. It easy to operate, reliable and has full functions, making it a leader in the nation.It has been widely used in petrol, chemistry, metallurgy, artifice, gas transportation, biological medicine and water procession etc.
    Characteristics:

    Sensor types:electrochemical sensor
    4-20mA analog output(3+ channel) for direct communication to DCS system andRS485ModBusoutput
    Sensormodule design on -spot replacement s and automatically distinguish sensor fault and current display fault simultaneously.
    LED Display(LCD optional)
    Password verification for repeat operation, avoid fault operations.
    -40+70following compensationfor accurate detecting.
    Second grade visual alarms on-site and Relay(connected with audible/visual alarms or drive exhaust device).
    User-selectable alarm setpoint(s).
