The GM700 laser gas analyzer offers efficient process analysis with high reliability and accuracy, even in challenging conditions. Using tunable diode laser spectroscopy, it measures various gas components like NH3, HF, HCl, and H2O through specific light absorption. Reliability, accuracy and very short response times are the decisive features of the GM700 laser gas analyzer. In-situ. and emission monitoring. Thanks to its innovative in-situ measuring technology, the analyzer can be mounted at the measurement location directly in the duct thr ugh which the. The GM700 series offers new possibilities to measure difficult and selective gas components such as HF, HCL or NH3 without the need of test gases. The benefits: time and cost savings thanks to simple installa-tion and.
