Evaluation of an Exposed Electrode Galvanic Cell Dissolved Oxygen Analyzer Used in Breweries. P. Takacs and E. L. Van Engel, Blitz-Weinhard Division, G. Heileman Brewing Co., Portland, OR 97209. J. Am. Soc. Brew. Chem. 42:0149, 1984.

Exposed electrode galvanic cell instruments used for dissolved oxygen analysis of beer were studied for accuracy and range, variation among instruments, drift, and the effect of pH. Results show that exposed electrode galvanic cell oxygen analyzers are too variable and unstable to reliably measure µg/L range dissolved oxygen in beer.
