• AUTOCAL with ambient air (dependent on the measured component)
  Highly cost effective because calibration gases are not required
• High selectivity thanks to multi-layer detectors, e.g. low cross-sensitivity to water vapor
• Sample chambers can be cleaned as required on site
  Cost savings due to reuse after contamination
• Menu-assisted operation in plaintext
  Operator control without manual, high level of operator safety
• Service information and logbook
  Preventive maintenance; help for service and maintenance personnel, cost savings
• Coded operator level against unauthorized access
  Increased safety
• Open interface architecture (RS 485, RS 232, PROFIBUS, SIPROM GA)
  Simplified process integration; remote operation and control

Special benefits when used in biogas plants

• Continuous measurement of all four important components, including H₂S
• Long service life of the H₂S sensor even at increased concentrations; no diluting or backflushing necessary
• Introduction and measurement of flammable gases as occurring in biogas plants (e.g. 70% CH₄), is permissible (TГњV certificate)
