On line monitoring system for tail gas of natural gas boiler

• electrochemical no/no2/nox/o2 sensor is adopted, and 24 bit high-precision chip is adopted for AD

• eight inch wide touch screen display

• built in NOx analysis module

• pretreatment system composed of built-in flowmeter, dust filter, condenser, etc

• with data storage function

• it has the functions of automatic test, self inspection, fault alarm, screen display, result query, etc

• Modbus communication can be connected to the upper computer, compatible with the conventional control output mode: 1 channel of 4~20ma current, 2 channels of relays, and audio-visual alarm output

• Chinese operation interface

• rainproof and dust proof housing design

The on-line monitor for NOx in the tail gas of combustion engine is mainly

used to monitor the concentration of NOx in the tail gas of small boilers and low nitrogen burners.

It is widely used in the monitoring of NOx in the tail gas of VOCs treatment by combustion method, and the on-line monitoring of NOx concentration in thetail gas

generated by the combustion of low nitrogen burners.

It is widely used in petroleum, chemical industry, printing, rubber products, plastics, medicine, electronics, industrial coating and other industries.
