Baume Hydrometer, Hydrometer acc. to Baumé or  Be

The  hydrometer according 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 a 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 careful 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 !
