SONIMIX 7050
Gas mixer
The Sonimix 7050 is a simplified gas mixer based on the principle of gas stream through mass flow controllers (MFC) and mainly used to calibrate and linearize Gas Monitors. Built according to the ISO 6145/7 normalization, the Sonimix 7050 is totally compatible with the US EPA methods and can be easily linked with National Standards (NIST, METAS, UKAS…).
The Sonimix 7050 Multi range gas mixer performs a large range of gas mixtures from high concentration gas cylinders

How many calibration points can it automatically handle for analyzer linearity verification?
Depending of the use technology, we can start from 10 points and go up to an infinite number of points.
Does the system generate static or dynamic gas mixtures?
Our system are dynamic gas mixer.
Calibrator or gas mixer: which one should you choose based on your application?
The term “calibrator” is often used when the primary application is the calibration of a gas analyzer or sensor. The term “gas mixer” is more commonly used when the objective is to generate a specific gas mixture.
Generating a gas mixture can serve different purposes, such as supplying an instrument, simulating a process gas, or calibrating an analyzer or sensor. In many cases, a gas mixer and a calibrator are essentially the same device, with the terminology depending mainly on the intended application.
Is it suitable for audit or official regulatory inspection environments?
Yes, all systems can be linked to the national standards.
Does the system require periodic maintenance or frequent recalibration?
The Sonic Nozzle technology provides unmatched stability, resulting in minimal drift and a recommended service interval of two years.
Does the system reduce logistics and gas storage costs?
Yes, our gas mixer helps reduce the number of gas cylinders required. Using a single high-concentration gas cylinder, the gas mixer can generate multiple concentration levels by dilution with a carrier gas.
This reduces the number of cylinders needed, lowers costs, and simplifies the associated logistics and cylinder management.
Can the system operate in continuous mode (24/7)?
Some customer are running our system in their production (24/7), no problem.
Can solenoid cylinder switching valves be directly controlled via the software?
Yes, all valves within the system are controlled automatically by the software.
Does the software log all events (flows, cylinder changes, errors) to ensure traceability and audit compliance?
Yes, the log allows to track the operational events.
Is it possible to program automatic multi-point calibration sequences?
Yes, all devices include a sequence mode which allows to build a calibration sequence to automatize a calibration process.
Is an accredited calibration certificate provided for the entire system?
LNI Swissgas is accredited according to ISO/IEC 17025 for flow measurement calibrations. An ISO/IEC 17025 calibration certificate can be supplied with every device.
