GM700 In-Situ gas analyser – EMS
GM700 In-Situ gas analyser

In-situ analyser for HCL,HF,NH3

High reliability and precision as well as minimal response times are the distinguishing features of the GM700 laser gas analyser. Based on the principle of TDLS (Tunable Diode Laser Spectroscopy) and by using specific light absorption, the GM700 is able to measure several gas components, such as NH3, HF, HCl or H2O. The in-situ measurement is ideal for the fast determination of gas concentrations in process control and emission monitoring.
