Gas mixing device

Stationary / Portable gas mixing device

Gas mixing devices are used for high precision control of gas mixtures in calibration procedures and preparing gas mixtures for industrial or laboratory use. Precise dilution of various gases enables the user to obtain the most accurate gas mixture for the used application. The user simply sets the target output concentration for the desired gas. Actual concentrations based on ﬂow measurements are displayed in real-time during mixing.

Applications

Gas mixtures for sensor calibration;
Calibration of personal gas monitors;
Calibration of emission & imission monitors;
Gas mixtures for industrial, laboratory use;
Applicable also in biotechnology, pharmacy, chemical, and biological experiments.
