IN SITU gas analyser GM700 - SICK

Measurement of gaseous components under difficult conditions In-situ and extractive technology.

High reliability and precision as well as minimal response times are the distinguishing features of the GM700 Laser gas analyzer. Based on the principle of TDLS and by using specific light absorption the GM700 from SICK is able to measure several gas components, such as NH3, HF, O2 or HCl.

The in-situ measurement is ideal for the fast determination of gas concentrations in process control and emission monitoring.
