MGP2 laboratory reference gas mixer


MGP2 reference gas mixer allows to blend up to 8 gases. Users can prepare any mixture of gases in matter of seconds thanks to touch screen interface. Precise, ergonomic, safe. Homogeneity of the mixture is guaranteed by a patented method.

There are processes, both in industry and in laboratories, in which the handling of industrial gases is necessary. One of the most common operations is the dilution or mixing of two or more input gases. To carry out these operations, industries or laboratories can be equipped with different more or less complex devices that allow the handling of these gases.

The solution developed by Gometrics allows handling operations to be carried out with a single instrument that is very easy to install and commission. The MGP2 is a device that allows the user to optimally perform the gas mixtures required for his application.

In its design, priority has been given to precision, versatility, ease of use and safety. Special emphasis has also been placed on the user interface to enhance usability and ergonomics.
