The ULTRAMAT 23 by Siemens is a gas analyzer that combines UV and NDIR (Non-Dispersive Infrared) technology to provide precise measurement of up to three IR-active gases. It also includes optional electrochemical sensors for detecting oxygen (O₂) and hydrogen sulfide (H₂S), making it highly versatile for various industrial applications. This multi-component analyzer is not only cost-effective but also space-efficient, ensuring reliable performance in continuous process gas analytics.
