AIR STILL HYDROMETER =SMALL= PROOF and TRALLES Hydrometer for use with AIR STILL COPPER PARROT

Description

This instrument will determine the direct percentage of alcohol in liquids with a specific gravity less than zero.  Just put a sample of unsweetened liquid containing alcohol in a test jar (dollar store bud vase, mason jar, or see my other items) and float the hydrometer in the liquid.  Take the reading at the bottom of the meniscus so that the level is even with the rest of the liquid.  We suggest that one time you measure some quality 80 proof factory hootch so that you understand exactly where to read the instrument.  Where it reads 80 is where you will read the unknown stuff.

The hydrometer is blown glass and fragile so be careful not to let it bounce off the bottom or sides and be careful closing the protective case so you don’t crush it.  Spin the hydrometer gently to release any bubbles that are sticking to it.  At eye level read the number off the scale where the hydrometer emerges from the liquid.  Be sure to read across the bottom of the ‘smile’ formed by the the meniscus (bottom of the curve).  This will be right at the level of the majority of the liquid.  The liquid kind of crawls up the side of the instrument and you don’t count that.
