Smoke is a mixture of gas and soot, and it is the main cause of air pollution in residential areas
.
The composition of flue gas is very complex.
Recently, the new measurement standard "flue gas sampler verification device" of Suzhou Metrology and Testing Institute successfully passed the measurement standard assessment and obtained the measurement standard assessment certificate
.
The measurement standard can carry out the verification and calibration of the flue gas sampler with a measurement range of (100~2000) mL/min
The flue gas sampler uses the Pitot tube isokinetic sampling weight method to capture particulate matter in the pipeline, and uses constant potential electrolysis to statutory and quantitatively determine harmful gases.
It can be used by environmental protection, health, labor, safety supervision, military, scientific research, education and other departments Measurement of the emission concentration/total amount of smoke and dust (gas) of various boilers and kilns and the efficiency of equipment dust removal and desulfurization
.
It can measure flue gas pneumatic pressure, flue gas static pressure, pressure before flow meter, temperature before flow meter, flue gas temperature, moisture content, O 2 , SO 2 , CO, NO, NO 2 , H 2 S, CO 2 , uniform suction flow rate and so on

The method of manual tracking is adopted.
As long as the flow reading of the constant velocity sampling on the microcomputer display of the instrument is adopted, we can quickly realize the adjustment in a short time
.
Practice has proved that this method is fast, intuitive, reliable, and has a small constant velocity tracking error
