Overview

Tailor-made gas analysis for process and emission monitoring

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.

At a glance
  • 6 different analyzer modules: DEFOR (NDUV, UVRAS), MULTOR (NDIR), OXOR-E (electrochemical O2), OXOR-P (paramagnetic O2), THERMOR (TC), and UNOR (NDIR)
  • 4 different types of enclosures
  • Gas module with sample gas pump and/or control sensors
  • New enclosure type for easy and quick integration in analyzer systems
  • Remote diagnosis via Ethernet with SOPAS ET software
