Best in class Gas Mixer with the unique sonic nozzle technology

The Sonimix 2106 is a gas mixer mainly used to calibrate and linearize gas monitors and to generate specific gas mixtures .
The Sonimix 2106 is based on the principle of gas flow through sonic nozzles and is built according the ISO 6145/6 standard. The sonic nozzle principle makes it the most accurate and stable device on the market. It generates binary mixtures from 0 to 100% in fixed steps in a pure mechanical process without electronic regulation and without any influence from ambient pressure or temperature.
The touch-screen LCD interface provides simple and user-friendly management of all functions on the unit.
Optional Auto Diagnostic functions for quick check of the instrument performances (patented) is available.
Optional Nox converter tester.
Proven metrological performances – Optional ISO 17025 calibration reports will be delivered from our accredited laboratory. In this way the device can be easily linked with National Standards (NIST, METAS, UKA, etc)
