fixed mounted QB2000N industrial Gas monitor

Characteristics:

•  ***0mA analog output for direct communication to DCS system,  RS**5 ModBus outputfor central unit

•  Relay output for connecting external device

•  LCD display screen(LED display screen optional)

•  Sensormodule(block) design on -spot replacement s and automatically distinguish sensor fault and current display fault simultaneously.

•  Password verification for repeat operation, avoid fault operations.

•  **0~**0°C following compensation for accurate detecting.

•  Second grade visual alarms on-site and Relay(connected with audible/visual alarms or drive exhaust device).

•  User-selectable alarm setpoint(s).

 

Note: QB***0N is with the digital display screen but QB***0T is without the digital display screen. The visual and audible alarm is optional.
