LGM Reference gas mixer for field use

In both industrial and laboratory settings, there are processes requiring the handling of industrial gases.

One of the most frequent operations is the blending or mixing of two or more input gases from standard gas bottles. In order to do this, industries and labs are equipped with gas handling devices of greater or lesser complexity.

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.
