GM901
|
|
| |
Gas analyzer for CO In addition to its modular concept – the Evaluation Unit can be deployed up to 1000 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).
Applications Process control, e.g. for monitoring fuel-burning plants in power plants, cement industry, steel industry or chemical industry.
