A deluxe hydrometer for beer or wine with built-in thermometer and correction scale that allows you to instantly correct your hydrometer readings for temperature. A hydrometer reads accurately at 20c. Temperatures above and below 20c require that you add or subtract from your reading. The scale is larger than a standard hydrometer making accurate readings far easier. The deluxe hydrometer also features three scales - specific gravity, potential alcohol and brix. 12.75" long (approx 324mm). Made in USA.
