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.
> Measure the O2 of gas and excess air coefficient.
> Evaluate and calibrate the accuracy of continuous flue gas measuring instruments.
> Other applicable occasions.

Features
> Designed to be integrated with the host and convenient for sampling.
> Equipped with titanium alloy vacuum heat insulation pipe, good heat insulation effect.
> Tested by UV Differential Optical absorption spectroscopy. It can measure the concentration of SO2, NOx, NH3 and cannot works affected by the water vapor in the flue gas,which is especially suitable for high humidity and low sulfur conditions.
> Automatically switch the range according to the high and low concentration values of SO2, NO and NO2.
> Equipped with pitot tube and smoke temperature sensor, it can measure smoke temperature flow rate and moisture content.
> Self contained battery≥3H.
> Dynamically save sampling data and spectral data, and export excel table.
> Built in condensate water removal module to prevent water from entering the sensor
