The LGM mixer designed by Gometrics takes a balance gas input and up to 3 standard gases. It comes with an optional battery and a suction hand grip for field use and has an internal pressure sensor to monitor the output pressure of the mixture at any moment. The homogeneity of the mixture is guaranteed by a patented mixing method.

The device allows the user to mix gases in the most suitable form for the application. The instrument can be delivered blind and without keyboard (when operating from PC) or with a simple human-machine interface to allow greater autonomy in field applications.

The LGM incorporates state of the art mass flow control technology.
