Field of application
The GMS800 is a product family of extractive gas analyzers which can measure more than 60 different gas components. The GMS800 is characterized by its modular design: 6 analyzing modules, one gas module, I/O modules and a control unit. Standardized 19” plug-in housings can be used for economical system integration. In harsh industrial environments, wall-mounted housings with approvals for Ex-zones according to ATEX are used.
Emission monitoring according to EN 15267 and process gas measurements, even in explosion-hazardous areas
Emission monitoring with very low concentrations
Measurement of sulfur compounds in process gases
Measurement of very low concentration in hydrogen or hydrocarbons
Device properties:
6 different analyzer modules
4 different types of enclosures
Gas module with sample gas pump and/or control sensors
New enclosure type for easy and quick integration
Remote diagnosis via Ethernet with SOPAS ET software
Benefits
Suitability tested according to EN 15267 and EN 14181
Installation in non-explosion-hazardous areas and explosion-hazardous areas (Zones 1 and 2 according to ATEX) possible
Modular design for minimum service and maintenance as well as easy upgrading of existing installations
Adjustment possible without test gases via optional adjustment unit
Influence of ambient temperature very minimal thanks to thermostatic measurement modules
