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 !
