SONIMIX 6000 C1

The multigas Sonimix 6000 C2 calibrator is designed to calibrate manually or by remote control up to 6 monitors installed in an air pollution monitoring station, for parameters such as SO2, HC, BTX, CO, NOx and O3.
The Sonimix 6000 C2 includes Mass Flow Controllers, GPT, ozone and self re-generable zero air generator and is equipped with
– an inlet for high concentration mixtures of diluted gases such as NO, NO2, SO2, CO, HC, BTX or mixtures of several compatible pollutants in the same cylinder.
– a zero air generator composed of an internal compressor with self re-generable filters, removes following components: moisture, O3, NOx, SO2, HC, BTX and optionally CO and CH4.
– a binary gas dilutor of two inlets (diluted gas and air), including 2 Mass Flow Controllers to generate the zero and other dilutions ratios going from 1/100 to 1/1000 (other values upon request).
The input pressures are monitored by two pressure switches. The ozone generator is regulated by UV-light feedback and is compensated from the atmospheric pressure and ambient temperature variations. It includes alarm on the UV power drift as well as the circuits for the Gas Phase Titration (GPT).

The multigas calibrator with GPT, ozone and self re-generable zero air generator, Sonimix 3012/3022, is an instrument designed to calibrate manually or by remote control up to 6 monitors installed in an air pollution monitoring station, such as SO2, HC, BTX, CO, NOx and O3.
The Sonimix 3012/3022 is equipped with
– an inlet for high concentration mixtures of diluted gases such as NO, NO2, SO2, CO, HC, BTX or mixtures of several compatible polluants in the same cylinder.
– a zero air generator composed of an internal compressor with self re-generable filters that removes moisture, O3, NOx, SO2, HC, BTX and optionally CO and CH4.
– a binary gas dilutor with two inlets (diluted gas and air), based on sonic nozzles (ISO 6145-6 standard)
The ozone generator is regulated by UV-light feedback and compensated from the atmospheric pressure and ambient temperature variations, with alarm on the drift of UV-light as well as the circuits for the GPT.

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.

The Sonimix 2130 NOx converter tester has been designed to generate a stable NO2 concentration with a small reaction time. It is based on the sonic nozzles technology (ISO 6145-6 technology) and high stability pressure regulators.

 The NOx converter tester is often used together with a multi-steps gas divider also based on sonic nozzles and high precision pressure regulators.

 In order to validate NOx measurements, the efficiency of the NO2 converter must be higher than 90 %, it is therefore very important to check easily and precisely the efficiency of the NO2 converter.

 The SONIMIX 2130 converter tester is based on the process known under the name of Gaseous Phase Titration
