ULTRAMAT 23, Rack Device, 1 Channel
The Siemens ULTRAMAT 23 is a high-precision extractive gas analyzer designed for continuous measurement of infrared (IR)-absorbing gases. Built in a 19” rack-mounted format, it supports reliable monitoring in industrial, environmental, and process control applications.
Key Features
-
NDIR (Non-Dispersive Infrared) technology for high selectivity gas measurement
-
1-channel configuration (single IR gas component)
- Optional O₂ measurement via electrochemical sensor
-
AUTOCAL function using ambient air (reduced calibration gas need)
- Low cross-sensitivity (e.g., minimal interference from water vapor)
- Robust, cleanable measuring cells for long-term use
- Menu-guided operation with plain-text interface
- Integrated logbook for diagnostics & maintenance
