ZR-3211H UV DOAS Method GAS Analyzer
ZR 3211H Stack dust( gas) Tester by UV Differential Optical absorption spectroscopy is a portable instrument,which can measure the concentration of SO2, NOx, O2, NH3. It cannot works affected by the water vapor in the flue gas,which is especially suitable for high humidity and low sulfur conditions. The instrument is designed to be integrated with the host and convenient for sampling. 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.
Applications
> Measure the O2 of gas and excess air coefficient.
> Evaluate and calibrate the accuracy of continuous flue gas measuring instruments.
> Other applicable occasions.
