Model 7873​​​

The model 7873 Oxygen Analyzer is a Zirconia analyzer designed for the analysis of combustion gases. It measures the residual concentration of Oxygen in the fumes produced by combustion processes that is the quantity of residual Oxygen after the complete oxidation of the fuel.

The Instrument features a special Zirconium Oxide sensor with reference to the solid state (consisting of a special mixture of metals and their oxides) eliminating the need for a reference air flow.
