Alkoholmeter, Alcohol tester

The alcoholmeter measures the alcohol percentage in alcohol / water liquid only ! If you have sugar in your liquid you will get an uncorrect reading.

The most common types  of alcoholmeter are according to:
weight %, volume %  or previously acc. to Tralle %, proof %,  Gay-Lussac % and Cartier.

Alcoholmeter acc. to vol. % are based on the alcohol % of the volume. This means that in case of a 100 Liter alcohol / water liquid of 20 ° C / 68 ° F and a reading of 50 vol %, you get 50 Liters of pure alcohol at 20 C / 68 F and the rest is water. The vol % alcoholmeter 20 ° C today corresponds exactly to the alcoholmeter acc. to Gay-Lussac 20 ° C / 68 ° F.  A proof scale is twice of vol %.  A weight % or gew.% scale is based on 1 kilogram out of 100.  In case of a measurement of 50 Wt.%, 50 kilograms are pure alcohol and the rest is water. Nearly every country has its own alcoholmeter or a special one !

Combined alcoholmeter with encorporated thermometer are very usefull and  give a more correct reading. The reason is:
1. The thermometer has the same scale error as the alcoholmeter.
2. The thermometer floats very deep and in the central of the liquid.
3. During reading the alcoholmeter, the liquid in the bulb and in the capillary
    has time to rise to the temperature the test liquid has.

How to use: For using an alcoholmeter you require a test jar to make an exact and easy reading! Before and after use clean the alcoholmeter and test jar with warm water and dry before use. The alcoholmeter should also be wiped dry with a linen cloth. After cleaning, the alcoholmeter 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 you have strong alcohol in your testing liquid ! The alcoholmeter is now dipped slowly into the liquid until it floats freely. The hydrometer has to be free of bubbles! Do not let the alcoholmeter 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!
