  • cant believe there is no comments on this. Nice video, really shows how bad the floating arm hydrometers really can be. 1.025-1.029 is a pretty big window for error.

  • thanks for the comment, these videos were done very quickly to solve some needs for my online lab class. I will go back later and edit/improve.
