IMulti-gas is a calibration instrument for online atmospheric monitoring and industrial control field online analysis of high-precision gas analyzer. It is a precision gas calibration instrument based on microprocessor control. It is mainly used for calibration of environmental air quality continuous automatic online monitoring system analyzer, and can also be used for quality control of laboratory and gas analyzer production.
The basic unit of the dynamic calibrator is two high-precision mass flow controllers, and modules such as ozone generator, ozone photometer and penetration furnace can also be selected according to user needs.Calibrator uses two high precision mass flow control device to match the standard gas, and produces nmol/mol~μmol/mol (ppb~ppm) grade standard gas through the method of thin release. The instrument can use up to three standard gases at the same time.The multipoint linearization curve is used to control the ozone generator to ensure repeatability of the ozone concentration.Selectable photometer accessories enable precise control of the ozone generator during calibration and meteorological titration (GPT). Ozone generators produce ozone standard gas by gas phase titration in the internal reaction with NO standard gas to produce NO2 gas.
