MFC Gas Mixer

The Sonimix 7100 is a gas mixer mainly used to calibrate and linearize gas monitors and to generate specific gas mixtures .
The Sonimix 7100 is based on the principle of gas flow through MFC (Mass Flow Controllers) and is built according the ISO 6145/7 standards. This instrument provides a very high flexibility allowing to combine multigas mixtures (up to 5 gases + a balance gas) and multi-range functionality.
The touch-screen LCD interface provides simple and user-friendly management of all functions on the unit.
All models make automatic calculation in 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.
