ZR22S, ZR202S Explosionproof Zirconia Oxygen Analyzers

Two types are available for an explosionproof direct in situ zirconia oxygen analyzer. Model ZR22S/ZR402G is a separate type which consists of a ZR22S explosionproof probe and a ZR402G non-explosionproof converter.

Model ZR202S is an integrated type which combines a probe and a converter. Both Zirconia oxygen analyzers do not need a sampling device, and allow direct installation of the probe in the wall of a flue or furnace to measure the concentration of oxygen in the stack gas. The converter displays the cell temperature and cell emf in addition to the oxygen concentration.

This analyzer is most suitable for monitoring combustion and controlling the low-oxygen combustion of various industrial furnaces in such explosive atmospheres as at petroleum refineries, petrochemical plants, and natural gas plants.
