Hydrometer (3 Scale)

A must-have for all brewers, whether amateur or professional. Look no further than a reliable hydrometer for precise and straightforward measurements. This tool accurately measures liquid density or specific gravity, providing a reading for your wash's gravity. Simply suspend the hydrometer in a sample of your wash and use one of our 250mL glass cylinders or 100mL plastic cylinders for the reading.
To calculate your % Alcohol By Volume 
(OG - FG) x 131.25 = ABV %
Where OG is your Original Gravity e.g. 1.050 as shown by your hydrometer before you pitch your yeast.
and FG "Final Gravity" e.g. 1.010 as shown by the hydrometer after it has fermented.
= ( 1.050 - 1.010 ) * 131.25 
= 5.25% ABV
