The Siemens ULTRAMAT 23 is a cost-effective multicomponent analyzer for the measurement of up to 3 infrared sensitive gases (carbon monoxide CO, carbon dioxide CO2, methane CH4, nitric oxide NO, etc.) using the non dispersive infrared (NDIR) principle, plus oxygen (O2) using an electrochemical or paramagnetic measuring cell, and sulfur dioxide (SO2) using ultraviolet (UV) absorption. The ULTRAMAT 23 is suitable for a wide range of standard applications, such as emission monitoring, biogas analysis, room air monitoring and other process applications. Calibration using ambient air eliminates the need to use calibration gases for extended periods.
