Laboratory Ozone Generator

The Sonimix 4001 is a stand alone ozone primary transfer standard able to generate ozone together with dry or wet air (optional) allowing to calibrate the ozone monitors in several points. It generates an outflow of 3 Nl/min air containing 10 to 1000 ppb O3, with stability and reproducibility of the concentration better than 1% relative. The extended range model generates 10 ppb to 10 ppm at 3 L/min and 10 ppm to 35 ppm at 0.9 L/min.

The Sonimix 4001 is using pressure regulator and sonic nozzles and an ozone generator including thermostatisation and regulation by UV light photometer measurement with atmospheric pressure and temperature corrections (US EPA method of UV absorption by ozone, Beer-Lambert law). The ozone analyser is built with 1 reference UV light detectors that measure in alternance the UV intensity without any ozone and then the same UV light but through the generated ozone. With these 2 values, the processor calculates the amount of ozone generated.
