ECOM-D portable flue gas analyzer is suitable for measuring and analyzing the combustion measurement of various industrial combustion devices and industrial boilers, and detecting the combustion state, so as to optimize the combustion, save energy and reduce the emission of polluting gases. The instrument has the advantages of humanized design, friendly interface, simple operation and maintenance. As a combustion and boiler measuring equipment, the instrument has strong functions, light weight, portable structure and easy to carry. It can analyze and measure multiple parameters at the same time. It is an ideal equipment for environmental monitoring and boiler adjustment. Continuous monitoring: O2, Co, CO2, no, SO2, NO2, H2S and flue gas temperature, ambient temperature, pressure, flue gas dew point, combustion efficiency, exhaust heat loss, air excess coefficient, flue gas dew point, ppm, mg / m3, reference oxygen conversion, etc. 2. The product is suitable for testing and adjusting the combustion process analysis of industrial boilers and burners, and emergency monitoring of fixed pollution source emissions; The instrument is equipped with corrosion-resistant PTFE sampling pipeline, sampling probe, multi-stage smoke filter, stainless steel Peltier gas cooler, peristaltic pump and electronic detection of condensate. Once the emission limit value is reached, the condensate will be automatically opened to discharge to the outside of the instrument. It is very suitable for monitoring high humidity and high dust boiler occasions.
