ZR 3211C Stack dust( gas) Tester by UV Differential Optical absorption spectroscopy is a portable instrument. It can measure the concentration of SO2, NOx, O2, H2S, CO, CO2 and other gases by UV Differential Optical Absorption Spectroscopy. It cannot works affected by the water vapor in the flue gas,which is especially suitable for high humidity and low sulfur conditions. It can be used by environmental departments to test the gas concentration and emission from boilers, and can also be used in industrial and mining enterprises to measure the concentration of various harmful gases.
> Measurement of SO2 and NOx emission concentration, converted concentration and total emission of all kinds of boilers, industrial furnaces.
> Evaluate and calibrate the accuracy of continuous flue gas measuring instruments.
> Measure flue parameters (dynamic pressure, static pressure, temperature, flow rate, standard dry flow, etc.
> Measure the O2 of gas and excess air coefficient.
