SONIMIX 3012/3022

Multigas calibrator with GPT, ozone & self re-generable zero air generator

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.
