Compact gas diluter with a smart software

On-site customised gas standard preparation has never been easier than with Zephyr – a compact version of well-known GasMix™ gas mixers/diluters from AlyTech. This compact device is a smart companion in quality assurance for all gas analysers, GC or gas detectors helping you significantly reduce your stock of gas standard cylinders and related cost.

Compliant with the ISO6145-7 international standard method “Gas analysis -- Preparation of calibration gas mixtures using dynamic volumetric methods” the Zephyr is a very cost efficient solution for creating a multi-point calibration curve from a concentrated gas standard and a diluent. This diluter is compatible with aggressive gases and active compounds like sulphurs gases, ammonia and VOCs .

With its touch screen and intuitive interface the device is very simple in operation. The unique Smart Sequence building feature helps the operator to make multi-point calibration curves easily: Just choose the number of points, starting and ending concentration values, and the software calculates the respective flow rates. The sequence is stored in the memory and recalled at any time.

When it is used for the calibration of an analyser, the accuracy of generated gas is very important. The uncertainty of the final gas concentration is calculated automatically taking into account the actual used flow and the certified uncertainty of the parent gas. With flow accuracy ±0.5% of the set point all over the scale the Zephyr adds very little dilution error while offering very wide dilution ratio up to 10000

With its small foot print, imbedded smart software and optional internal battery (up to 8h autonomy) it can be installed where you need it, in the lab, in the field or in a mobile lab.
