Oxygen trace analyser Oxystem S.

Application
Monitors inert gas atmospheres for absence of oxygen in order to prevent oxidation. Measurement of residual oxygen concentration in the production of noble gases and nitrogen.
Oxygen measurement without cooling (hot measurement); the system can process gas directly at temperatures of up to 350 °C.

Description
The sensor is based on the principle of solid electrolytes (zirconium dioxide). The free oxygen ion movement begins at temperatures of more 500 °C (solid electrolyte potentiometric method).
The sensor is heated. The oxygen concentration is calculated from the cell voltage and the temperature according to Nernst's law. The analyser is designed as a 19“ rack mounting unit 3 HU, 84 DU. All components are integrated in a single housing. The electronic system is operated via keypad and display.
The ranges % by volume, ppm and e xx % by volume O2 are fully automatically switched over on the display. The menu item "Error status" provides more detailed information on the self-monitoring functions. All status and alarm messages are indicated on the front (display with blinking exclamation marks) and output via a voltage-free changeover contact.
