Advance Optima AO2000
Integrated analyzer system solution

Advance Optima series with a modular system design. Broadest range of analysis technology from specialized process photometers to in-line laser measurement. Centrally and remotely operable with Ethernet networks. Designed for use in hazardous areas and with flammable sample gases.

Analyzer Module


The Advance Optima process gas analyzers have a modular design that offers a long-term security in your investment. Analyzer modules can be freely combined into tailor-made solutions and upgraded or extended with new features at any time. Remote modules are easily attached and centrally operated.
The advantages to you – Advance Optima offers:
  • One central unit and up to 4 analyzer modules
    – with common control
    – with a common connection technology
    – in a common system housing
  • All analyzers use high performance measurement technology
    – Photometers
    – In-Situ Laser Analyzer
    – Oxygen Analyzer with new microwing technology
    – Oxygen Analyzers
    − Trace Oxygen Analyzer
    – Thermal Conductivity Analyzers
    – FID Analyzers
  • Multiple analyzer systems: up to four analyzer modules with up to six sample components in one system
  • Extensive automatic calibration with air or integral calibration cells, no need for test gas cylinders
  • Self-monitoring function indicates when maintenance is required
  • Hazardous location approved models in accordance with international standards
  • “Safety Concept” for measuring flammable gases in Zone 2 , Category 3G
  • Provides Ethernet TCP/IP interfaces, OPC server, PROFIBUS and Modbus interfaces
