Alcohol Meter

[Nebe]

I love google

From the 18th century until 1 January 1980, the United Kingdom measured alcohol content in terms of "proof spirit", which was defined as spirit with a gravity of 12/13 that of water, or 923kg/m3, and equivalent to 57.15% ABV .[1] The term originated in the 18th century, when payments to British sailors included rations of rum. To ensure that the rum had not been watered down, it was "proved" by dousing gunpowder in it, then tested to see if the gunpowder would ignite. If it did not, then the rum contained too much water and was considered to be "under proof". Gunpowder would not burn in rum that contained less than approximately 57.15% ABV. Therefore, rum that contained this percentage of alcohol was defined to have "100° (one hundred degrees) proof".

I have no issues with using a hydrometer nor the alcohol meter. I have both, took a preliminary reading with the hydrometer and a close to 'full-fermentation-cure' reading to calculate the results (will do it again when I know it's done for sure, my air-lock still burps every 2 hours or so).

Luckily the scale on my alcohol meter has a suitable range for cross-checking the hydrometer. The results are deathly close, so I'm happy

However, the Aerometer scale does not match any reading on the other 2 meters. I can't make the correlation??? Not even sure what the numbers stand for AND they read in reverse??? When I place it into the test cylinder, it reads 20. 3 scales on the hydrometer and 2 scales on the alcohol meter, nothing close to 20 anything?? Didn't know if anyone in here had used or seen one like this before. No big deal, like I said...someone had it hanging around and asked if I could use it (it's from the old country) guessing it was used to measure white lightening...,,,

I'm pretty much where I wanted to be, 15% or 30 proof, however you care to look at it,... cHeErs everyone!!!
