GM901 CO in situ gas analyser
GM901 CO in situ gas analyser
GM901 – Gas analyzer for CO
In addition to its modular concept – the evaluation unit can be deployed up to 1,000 m from the measuring point – the GM901 CO Analyzer is available as a cross-duct or probe version. As a result, the GM901 is ideally suited to a broad range of application, even for difficult measuring tasks (e.g. high dust concentrations, overpressure, “wet” flue gases, or extremely high measuring gas concentrations).
