Process gas chromatograph RGC 717
Do you want to measure and analyze the purity of your hydrogen? Our RGC 717 - the new member of the RGC 7 family generation - is available for this purpose. The gas components are processed in an analysis computer and used to calculate other values such as the calorific value, standard density, heating value and Wobbe index. The measuring range for the measurement starts at a hydrogen purity ＞ 97 mol% and gives you a reliable and accurate quality statement about the pure hydrogen."
The RGC 7 family has a new member! The analytical computer forms the digital interface for your end-to-end networked plant technology.
