Ultramat 23 (Multi-IR, O2)



Siemens Ultramat 23 (EN).PDF

The Siemens ULTRAMAT 23 is a cost-effective multicomponent analyzer for the measurement of up to 3 infrared sensitive gases using the NDIR principle, plus O2 using an electrochemical or paramagnetic Oxygen measuring cell.


The ULTRAMAT 23 is suitable for a wide range of standard applications, such as emission monitoring, combustion optimization, room air monitoring and other applications. Calibration using ambient air eliminates the need to use calibration gases for extended periods (up to one year).



  • AUTOCAL with ambient air (dependent on the measuring component) - Highly cost effective because calibration gases are not required
  • High selectivity thanks to multi-layer detectors, e.g. low cross sensitivity to water vapour
  • Cleanable sample cells - cost savings thanks to reuse after contamination
  • Menu-assisted operation in plain text - operator control without referring to the 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

MEASURED GASES: CO, CO2, CH4, C2H4, C6H14, SO2, NO, N2O, SF6, O2, H2S
