Oxygen analyser Oxystem 1800 High temperature version.

Application
Combustion control and control of the furnace atmosphere at high temperatures in furnaces used in the ceramics and aluminium manufacturing industries. Measurements taken directly in the gas with short response times.

Description:
The sensor of the probe 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 probe is heated by the gas atmosphere, it does not have its own heating. The oxygen concentration is calculated from the cell voltage and the temperature according to Nernst´s law.
The analyser consists of two components, the probe and the evaluation unit. The probe is mounted either horizontally or vertically (at temperatures of more than 1,200 °C). The evaluation unit and the probe are connected by a 2-core screened cable and a screened thermo compensation wire, type S (Pt/PtRh10). The maximum length is 20 m.
Operation via keypad and display. The display shows the current oxygen concentration in percent or ppm and the temperature of the measuring cell. The ranges automatically switch from % by vol. to ppm and to e xx % by vol. O2.
