GM901 CO In-Situ gas analyser
In-situ CO analyser
The GM901 CO gas analyser is available as a cross-duct or probe type. As a result, it is suited to a broad range of applications – even for difficult measuring tasks such as high dust loads, overpressure, critical flow profiles, or high measuring gas concentrations.
