Paramagnetic magneto mechanical oxygen analyzer electrochemical analysis

Not affected by the pressure of the sample gas, the measurement is carried out through pre-treatment, pressure reduction, water removal, dust removal and other methods, with higher accuracy than zirconia.
The price is also expensive, and maintenance for pre-processing is the main work, which also requires some spare parts support.
In heating furnace applications, such instruments can also be used for measurement and should have a wider range.

Electrochemical method is a method of measuring oxygen concentration based on the principle that oxygen undergoes redox reactions on electrodes. The electrochemical sensor in an oxygen concentration analyzer typically includes a reference electrode and a working electrode. On the working electrode, oxygen undergoes a reduction reaction, generating an electric current. The magnitude of this current is directly proportional to the oxygen concentration, so the oxygen concentration can be calculated by measuring the magnitude of the current.
