New Automated and Portable Calibration Gas Generator

AlyTech has launched a unique engineered product combining a zero air generator, dual oven permeation device and accurate diluter into one compact instrument called PerMix ATMO. This is a cost effective solution created for the environmental market for on-site calibration and linearity checks of toxic gas detectors, automated measuring systems (AMS) monitoring emissions of NO2, SO2, CO, BTEX, H2S, other gas analysers and chromatographs.

This all-in-one portable device with built-in battery assures complete autonomy of operation for field use, mobile labs and remote locations. It doesn’t require any compressed gas cylinders; offering convenience of use, saving space, cost and removing safety hazard.

Equipped with a large touch screen and user friendly software the instrument’s operation is simple. The software enables flexible programming of the calibration sequences by defining oven temperature, flow, dilution rate, number of repeats as required.

For example, to assess the linearity of an analyser in full measuring range, a set of six concentrations: 80%, 40%, 0%, 60%, 20% and 95% can be pre-configured in the software and saved as a test sequence. For a repeatability check, three concentration levels (zero, 95% and national calibration concentration) are programmed with necessary number of repeats. When connected to the analyser, the unit will generate complete calibration program fully automatically without operator intervention.

High accuracy and reproducibility in generating calibration gas at variable concentrations make the PerMix ATMO an accomplished tool, with solid metrological performance.
