Brief introduction:
Ethylene oxide(ETO) is poisoned gas,which is widely used in
pharmacy, decontamination for medical supplies etc.
QB2000N is stationary gas detection and monitoring device. It is
sensitive to toxic gas such like ethylene oxide ETO gas.
It detect gas by use of natural diffusion, not by pump.
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. It
has been widely used in petrol, chemistry, metallurgy, artifice,
gas transportation, biological medicine and water procession
etc.
Characteristics:
◆4-20mA analog output for direct communication to DCS system
◆Relay output for connecting external device
◆LED display screen
◆Sensor module(block) design on -spot replacement s and
automatically distinguish sensor fault and current display fault
simultaneously.
◆Password verification for repeat operation, avoid fault
operations.
◆ -40～+70℃ 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).
