Abstract
The use of zirconia amperometric pump-gauge sensors with reference ele ctrodes for the qualitative and quantitative determination of oxygen, sulphur dioxide and nitric oxide was investigated. Corrosion of platin um electrodes occurred during operation in SO2 and NO atmospheres. Res ults suggested that electronic conduction was induced in the zirconia during operation in SO2-containing atmospheres. Characteristics in NO mixtures demonstrated encouraging conformance with theory.
