I have 2 alcoholometers here which gives completely different readings, the short eBay cheapie one is 10% different than the longer more expensive
Alla (France) Spirit Alcoholometer.
The big one would read 50%, the little one would read 40% in the same test jar, both calibrated to 20c
Which one is right, I figured the better quality one is the best to go off.
I figured one is not weighted correctly.
