Programmable Gas Blender - SONIMIX 7000

Supplier: Aust. Dynamic Technologies Co

The SONIMIX 7000 have been specially developed for the calibration and linearity checking of stack gas monitors.


The SONIMIX 7000 uses the latest technology of Mass Flow Controllers in order to generate simple or complex mixtures of gases with high accuracy and repeatability.

The SONIMIX devices have been designed with an integrated active purge system and the systematic suppression of dead volumes in order to obtain fast response time.

Using the SONIMIX 7000 it is possible to greatly decrease the number of cumbersome and expensive gas cylinders, which reduces the costs, saves time and reduces errors.

The SONIMIX 7000 is totally compatible with the US EPA methods and can be easily linked with National Standards (NIST, METAS, UKAS...). Each MFC is factory calibrated at 11 points by a traceable primary flow standards.

The internal processor interpolates these values in order to obtain high linearity. The internal processor calculates the concentration of the mixture and corrects the different gas flow in function of the nature of the used gases.

In addition the dilution steps are computed using the calibration data of each MFC. This method ensures an accuracy of 0.5% for each gas flow and an accuracy of 1.5% (of set point) for the concentration.

In order to save time, all critical parameters such as type and composition of alimenting gases, working units (%, ppm, ppb) are stored in the EEprom. The SONIMIX has an user frendly LCD interface.

The gas mixer can be used in a "flow mode" or "concentration mode". In addition, the recalibration and tracability of each MFC can be easily performed by the user with the "reference mode" (this particular menu is protected with a password).

The SONIMIX 7000 has also a RS 232 serial interface and a Windows based software is also available as option.
