Oxygen Probes are designed to provide a reliable measurement
of dissolved oxygen content in liquid steels.
A zirconia electrochemical cell, and thermocouple are combined
in one unit to provide the steel maker with a dynamic measurement
of the oxygen activity during the steel making process.
MinOX Probes are invaluable for process control during steel
production and prove a cost effective tool for ensuring
final product quality.

oxygen content in liquid steel
- The zirconium oxide electrochemical cell monitors the
partial pressure difference between the steel bath and
the known cell reference (Cr/Cr2O3) as EMF. Simultaneous
measurement of the temperature and the application of
Nernst´s law is used to provide the measurement
of oxygen activity (EMF = RT/nF *ln(pO2/pO1).
- Minox Oxygen Probes are available with thermocouples
types “S” (Pt-10%Rh/Pt), “R” (Pt-13%Rh/Pt) and “B” (Pt-30%Rh/Pt-6%Rh)
to IEC 584.
- The application range for active oxygen measurement
is between 1-2000 PPM with a reproducibility depending
on the specific conditions between ? 1 mV and ? 5 mV.
- MetNet Instrumentation, accessories and hardware complete
the system for active oxygen measurement.
