Description

SMART-OXZ Oxygen Analyzer uses a unique reference built-in zirconia technology, higher accuracy and repeatability oxygen measurement, no need to provide standard air and calibration.

Principle

The zirconia sensor is tubular, separated by a zirconia material in the middle, and porous metal layer are sintered on the two parts of the zirconia as electrodes (usually use platinum Pt as the electrode material). At a certain temperature (600°C~1400°C), oxygen molecules with higher oxygen content are adsorbed on the electrode, making this side electrode positively charged, which is the positive electrode or anode of the oxygen concentration battery. Under the catalysis of platinum, a reduction reaction takes place, get electrons to form oxygen ions. Oxygen ions migrate through a large amount of zirconia crystals to the other side where the oxygen content is low, making the electrode negatively charged, which is the negative electrode or cathode of the oxygen concentration battery. Lose electrons on the platinum electrode, forming oxygen molecules. In this way, a certain potential is formed on the two electrodes due to the accumulation of positive and negative charges. This potential is related to the difference in oxygen concentration between the two measured gases of zirconia. It conforms to the Nernst equation and then the oxygen partial pressure (P1) in the gas to be measured can be calculated, and the oxygen concentration in the gas to be measured is obtained.
