Description Precise gas mixtures can be achieved effectively and economically with the GM gas blending system. GMF series = fixed mix ratio GMM series = variable mix ratio GMA series = automatic mix ratio control As a fully automatic two or three gas mixer, the Cryotronix GMA system continuously monitors the output blend to provide an accurate analysis and alarms for deviations from set points. GM controls will ensure precise and homogeneous mixing of the input gases, at ratios which can vary from 0 to 100% independent of flow rate variations. Built in indicators and alarms make the GM gas blending system easy to use and highly reliable.
