Dynamic Gas Calibration Instrument Supply - Air Quality Automatic Monitoring System

Supply of dynamic gas calibrator

working principle

1. Dilution principle for gas distribution
Using precision mass flow controllers to control the dilution of standard gas or other source gases with zero air in steel cylinders.
2. Gas phase titration principle with gas distribution
Used to generate quantitative NO2 gas. The principle of gas-phase titration is based on the rapid reaction of NO+O3: NO+O3=NO2+O2. According to this reaction, when a known concentration of O3 is added to an excess of NO, the concentration of O3 is the concentration of NO2 produced, and the amount of NO2 varies with the amount of O3 added. Compare and obtain an accurate concentration of the mixed gas.
