How to use the alcohol meter:

Alcohol meters are used to measure the quality of distilled products. The method of measuring ABV (by volume) using a hydrometer is the same, but with one important difference: Measure ABV percentage using a hydrometer during fermentation Alcohol meters are used to measure the alcohol content after the fermentation process and after distilling the product with an alcohol still.

How the alcohol meter works:

We mentioned that because it has the same density as water, when sugar is added, it becomes too dense to stay under the water meter, which increases the hydrometer. With alcohol, it has the same density as alcohol and is lighter than water. This means that when you first insert it into a test tank, it will float on top. As the alcohol content in your test tank increases, the water meter no longer becomes overwhelmed and is getting lower and lower.

Before and during use: Alcohol meters are easy to use, but some steps need to be taken to ensure accurate readings. For example, when you first pull the meter out of a plastic case, you will want to wipe it off with a clean cloth. Please note that the end of the alcohol meter will have lead blocks. When operating the alcohol timer, make sure to always hold that end, as the grease on our fingers does mess up the reading. It is also recommended to sterilize the molded test cans before testing.

After thoroughly disinfecting both products, tilt the test tank at an angle and pour into the sample. This is to prevent most CO2 or oxygen bubbles from appearing during transmission. After inserting the alcohol meter into the test tank, you still need to grab the top of it and then gently rotate it in the alcohol to eliminate excess air bubbles. Make sure to fill the bottle only about 3/4 of the way up when pouring the sample, as the alcohol meter will cause the level to rise. Wait for all the liquid to settle, then the meter stops swinging. Also, make sure that the meter is free and not stuck on the side or bottom of the test tank. Simply match the scale's reading to the highest level in the tank When taking a reading, you will notice that you have two different measurement scales. One is the proofreading ratio and the other is the Tralle ratio. Tralle readings will always be half of the proof readings. This is your ABV (Alcohol Content) percentage. 

Several factors can interfere with your reading. Please note that any distilled spirit with a small amount of sugar will not give you the exact percentage. This means that liqueurs and spirits have been combined with flavors and sweeteners. When spirits are raw, be sure to test the alcohol content before adding any additives. The temperature of alcohol is best checked at 68F. If the temperature is too low or too high, the alcohol meter will not be able to give you an accurate percentage.
