Overview
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. Equipped with user-friendly software, the GMS800 features all the interfaces required for remote control via networks through to the connection to a distributed control system.
