GME700 Extractieve Laser gas analyser

GME700 Extractieve Laser gas analyser

GME700 – Quality process analysis

High reliability and precision are the distinguishing features of the GME700 Laser gas analyser. Based on the principle of TDLS (Tunable Diode Laser Spectroscopy) and by using specific light absorption the GME700 is able to measure several gas components, such as NH3, HF, HCl, H2O or O2. The compact 19″ unit includes the analyser and evaluation unit as well as a heated multipath measuring cell.
