Proof & Tralle Hydrometer

A proof and Tralle hydrometer is a tool used to measure the alcohol content in distilled spirits. It’s a glass device that you float in the liquid, and depending on how deep it sinks, you can read the alcohol level on the scale.

The proof scale shows the strength of the alcohol in "proof," which is a measurement used in the U.S. (proof double the alcohol percentage). So, if a liquid is 50% alcohol, it will read as 100 proof. The other scale, the Tralle scale, shows the alcohol by volume (ABV) directly —no conversion needed.
