Field of application
Reliability, accuracy and very short response times are the decisive features of the GM700 laser gas analyzer. Based on the TDLS (tunable diode laser spectroscopy) principle, the GM700 measures different gas components, such as NH3, HF, HCl oder H2O, by specific light absorption. In-situ measurement is particularly well-suited to the rapid determination of gas concentrations in process control and emission monitoring.
