Why is the measured value too high on my wtw OxiCal-SL Oxygen Equipment?

  Frances RodriguezAug 9, 2025
  If the measured value from your wtw Oxygen Equipment is too high, it could be due to a high share of solutes or air bubbles hitting the membrane with high velocity. Correct the solubility function by entering the salinity equivalent. Ensure the flow doesn't directly meet the membrane. Note that if the carbon dioxide pressure is too high (over 1 Bar), no measurement is possible.
