Why ULTRAMAT 23?

The ULTRAMAT 23 measures several gases simultaneously, with a choice of detection methods and sensors. The IR detector can measure up to three infrared-sensitive gases, and a UV LED can measure even the smallest concentrations of SO₂ and NO₂. Electrochemical sensors for O₂ and H₂S measurement are also available as an option. Due to this multi-component design, the ULTRAMAT 23 offers a high degree of economic efficiency and is widely used.

Simultaneous multicomponent gas measurement

Measure up to 4 gas components at once using proven NDIR technology for infrared-active gases and electrochemical sensing for O₂ — delivering comprehensive, real-time process insight in a single, integrated analyzer.

Compact, modular and scalable design

The ULTRAMAT 23's space-saving, modular architecture supports a wide range of accessories and configurations, making it easy to adapt to your specific application needs — from emission monitoring to process control.

Minimal need for maintenance

ULTRAMAT 23 uses ambient air for auto calibration, minimizing the need for test gases.

Featured capabilities

Emission monitoring as easy and accurate as it gets

Emission monitoring is key and ever-stricter laws and regulations require powerful, precise and reliable analytical measurement devices that are affordable and easy-to-use — such as the Siemens ULTRAMAT 23.

High selectivity due to multi-layer detectors

Multi-layer detectors support high selectivity and reduced water vapor interference. The measuring cuvettes are robust, resistant and easily cleaned in case of disturbances induced by faults in the sample preparation and subsequent contamination. The electrochemical oxygen sensor determines the O2 reference variable, and the hydrogen sulphide sensor extends the application range to biogas plants.
