Th-2008h multi gas dynamic calibrator is used to calibrate various ambient air analyzers. Two mass flow controllers (standard configuration) are built in to control the flow of zero gas and standard gas respectively. It is used with zero gas generator and various standard gases to calibrate SO2, no and co analyzers by diluting standard gas with zero gas. The built-in ozone generator and detection unit are used to generate O3 gas. The ozone concentration can be calibrated by standard ozone gas of fixed concentration and arbitrary concentration after 16 stage calibration. It can produce quantitative NO2 standard gas. The efficiency of NO2 → no conversion furnace in NOx analyzer is calibrated by gas phase titration method. The analyzer is calibrated by preset programming or random operation of users. After all calibration presets, standard gases such as SO2, no, NO2, O3, CO need to be quantitatively output with one button.
