Dynamic gas-mixing installation for calibrating and checking automatic gas analyzers

Conclusion

• 1. The dynamic gas-mixing equipment based on obtaining gas mixtures by means of rheometers with calibrated capillaries can be recommended for calibrating and checking calibrations of commercial automatic gas analyzers used for determining the content of sulfur dioxide.

• 2. Commercial gas analyzers which have an error of 3–10% can be calibrated by means of the gas-mixing equipment without a thermostat, since room temperature vibrations in the range of 5–7°C have virtually no effect on measurement results.
