TH-2008H Multi Gas Dynamic Calibration Instrument

　　working principle:
The TH-2008H multi gas dynamic calibrator is used to calibrate various environmental air analyzers. It is equipped with two mass flow controllers (standard) to control the flow rates of zero gas and standard gas, respectively. It is used in conjunction with a zero gas generator and multiple standard gases to calibrate SO2, NO, and CO analyzers by diluting the standard gas with zero gas. The built-in ozone generator and detection unit are used to generate O3 gas. The O3 concentration is calibrated in 16 stages, and the standard ozone gas calibration ozone analyzer can produce fixed-point concentration and any concentration. Quantitative NO2 standard gas can be generated, and the efficiency of the NO2 → NO converter in the NOX analyzer can be calibrated using gas-phase titration. Calibration of the analyzer can be completed through preset programming or user random operation. After all calibration presets are set, various standard gases such as SO2, NO, NO2, O3, CO that need to be quantitatively output can be completed with one click.
