Industrial Standalone 10V/220V ethylene oxide(ETO) Chlorine(CL2) / Ammonia(NH3) gas detector/alarm Analyzer

QB2000F All-in-One wall-mounted gas alarm is designed to monitor the gas leakage in the non-explosive environment continuously by adopting imported electrochemical gas sensors for toxic gas, oxygen while catalytic combustion sensor for combustible gas.
The alarm controller has excellent sensibility, quite good accuracy, linearity and receptivity; Big English LCD displays the real-time concentration of the leakage gas. With 2 relay output, once the concentration exceed the preset alarm point(threshold) it will start the acoustic-optical alarm and it can drive the external equipment like exhaust fans.; Through 4-20mA signal output, it can be directly connected into the factory DCS system, through RS4845 signal output, it can be connected with factory’s principle computer.

Adopts advanced 16 digit ultra-low power consumption embedded micro controller.
128*64 dot matrix ultra-large Chinese liquid-crystal display
Adjustable H-alarm and L-alarm values
Displaying the time of first alarm.
Real-time display
Replaceable sensor module design
Automatic calibrating to ensure the detecting accuracy.
200 pieces alarm record can be stored automatically
Password management
The internal battery backup can work continuously for 24 hours(no alarming status)
