COSA Xentaur


The Refining Industry is one COSA Xentaur’s main markets and we offer a wide range of measurement solutions for process as well as laboratory.

By understanding process and laboratory aspects of an application area, COSA Xentaur’s aims to provide the best possible and comprehensive service to our customers.

For dew point control, CosaXentaur’s HTF™ sensor technology can be trusted where other methods have routinely failed. The stability, accuracy and life expectancy of HTF™ sensors have set new a standard in the industry.

Dew point or moisture concentrations can have a very major effect on the quality of a process or final product and accurate dew point measurements are often of mission-critical nature.

For this reason COSA Xentaur offers both online and spot control moisture measurement systems for gases and liquids suitable for use in hazardous areas.

Laboratories in the refining industry have relied on CosaXentaur elemental analyzers for over thirty years. When it comes to the analysis of trace sulfur, nitrogen and chlorine our NSX-2100 series offer fully automated analyzer packages, following ASTM methods with unprecedented detection limits, accuracy and stability.
