Two Causes Resulting in Hydrometer Calibration Change

  • 1) The scale in the hydrometer stem could change position if subjected to severe mechanical shock or high temperatures. 2) Chemical attack of the glass sleeve. If the hydrometer is routinely used in alkaline or acidic solutions, then it is possible that over time the glass will be “chemically attacked.” When this happens, the glass will become very slightly to significantly opaque. Any change in the clarity of the glass will throw into doubt the accuracy of the hydrometer.
