XTP601 Series

Oxygen Analyzer for Safe or Hazardous Areas
A robust, linear and stable oxygen analyzer for measurements in gases such as hydrogen, nitrogen, biogas, or carbon dioxide. The sensor is housed in an IP66 rugged casing, making it suitable for a wide range of applications. When supplied with flame arrestors, the analyzer becomes explosion-proof and certified for use in hazardous areas.



Product Features
