Baume Hydrometer, Hydrometer acc. to Baumé or Be The hydrometer acc.to
Baume measure the percentage of acid, lye, sugar etc. content in a liquid of 15 ° C / 59 ° F .
The formula is for
heavy liquids: spec.grav. =
144,3 or Baume = 144,3 - 144,3
. 144,3 - Baume spec.grav.
Nearly every country has a special one of Baumé Hydrometer !
How to use:
For using an hydrometer you require a test jar to make an exact and easy reading! Before and after use clean the hydrometer and test jar with warm water and dry before use. The hydrometer should also be wiped dry with a linen cloth. After cleaning, the hydrometer should be held only from the thin part above the paper scale. The clean liquid is first poured into the test jar, leaving at least 2” / 5 cm from the rim free. Close the test jar with a clean plastic foil and with the palm of the hand, shake 10 times!
Be carefull if acid or lye is in your testing liquid !
The hydrometer is now dipped slowly into the liquid until it floats freely. The hydrometer has to be free of bubbles! Do not let the hydrometer fall into the test jar! The reading is taken at eye level at the spot where the thin part or stem intersects the liquid, i.e. at the level of the liquid surface. Record the temperature of the liquid. Take care of the temperature of room, liquid and instrument is the same. Store test jar,liquid, instrument about 4 hours in the same room you test !
