Modular System S700 – Gas analysis

ModularSystem S700 – Gas analysis with system

The S700 modular system is very easy to configure to provide a tailor-made application. An S700 housing can be equipped with up to 3 analyzer modules for compact and cost-effective system solutions. A total of 6 different analyzer modules are available for analyzing more than 60 gas components.

Depending on the measuring task, installation site, and ambient conditions, the following housing types are available:

  • S710 19″ rack for analyzer cabinets and standard applications
  • S715 wall-mounting enclosure for harsh application conditions and zone 2 explosive environment (ATEX)
  • S720 flame-proof housing for zone 1 explosive environment (ATEX)


  • 5 different measurement principles available
  • More than 60 measuring components to choose from
  • 3 different housing variants for different fields of application
  • Up to 3 analyzer modules in a single housing


  • Eenvoudige toepassingsspecifieke aanpassing door modulaire opbouw
  • Ook inzetbaar in explosiegevaarlijke omgevingen Zone 1 en 2 (ATEX)
  • Automatische instelling achteraf met testgas of kalibratiecuvet
  • Geïntegreerde zelfbewaking en foutdiagnose


  • Easy application-specific adaptation due to modular design
  • Also suitable for zone 1 and zone 2 explosive environments (ATEX)
  • Automatic adjustment with test gas or calibration cell
  • Integrated self-monitoring and fault diagnosis


  • Emission measurement according to 13th (2001/80/EC), 17th (2000/76/EC), and 27th German Federal Emission Protection Directive (BImSchV).
  • Cooling gas monitoring of turbo generators
  • Measurement of CO for coal mill monitoring
  • Purity measurement of H2 in pressure swing adsorption plants
  • Monitoring of CO2 in natural gas in natural gas conditioning plants
