Introduction

The basic unit of the dynamic calibrator is two high-precision mass flow controllers, and modules such as ozone generator, ozone photometer and permeation furnace can also be selected according to user needs, The calibrator uses two high-precision mass flow controllers to match the standard gas, and generates the standard gas of nmol/mol-µmol/mol (ppb~ppm) level by the method of proportional dilution. The instrument can use up to three standard gases at the same time. Road standard gas. A multi-point linearization curve was used to control the ozone generator to ensure repeatability of ozone concentration. An optional photometer accessory enables precise control of the ozone generator during calibration and meteorological titration (GPT). The ozone generator produces ozone standard gas, which can react with NO standard gas internally to generate NO2 gas by gas-phase titration method.
