Drift in the oxygen content measured with the Lex-O2-Con: long-term assessment.
After more than one year of intensive use (30 to 50 measurements a day) a drift was observed in the data given by two Lex-O2-Con analyzers. This was confirmed by iterative comparisons with the Van Slyke method. After recharge of the cells, the instruments seem to function again correctly.
