Best in class Gas Mixer with 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 a quick check of the instrument performances (patented) is available.
Optional Nox converter tester.

Proven metrological performances – Optional ISO 17025 calibration reports will be delivered by LNI’s accredited laboratory. In this way the device can be easily linked with National Standards (NIST, METAS, UKA, etc)

The touch-screen LCD interface provides simple and user-friendly management of all functions on the unit.

All models make automatic calculations in the function of the used gases types. The Sonimix 7100 is totally compatible with the US EPA methods and can be easily linked with National Standards (NIST, METAS, UKAS…)

Each mass flow controller is factory calibrated in 10 points by a traceable primary standard.
