The Alla Proof and Tralle Alcohol meter (alcometer) or spirit meter incorporates a thermometer.
This device is used to measure the strength and temperature of distilled spirits only, and will not work for wine or beer. If you are making spirits then this is the type of hydrometer you will need.
When floated in pure alcohol the meter will show the alcohol by volume (ABV). It will read up to 100% ABV.
Large, clear numbers make for easy use.
Supplied in a sturdy, rigid plastic case.
