  • Details
  • Reviews


The Herculometer is calibrated to 60°F (15.5°C).

Made of a durable polycarbonate plastic it’s virtually unshatterable (within reasonable limits, so let’s not push it!) The widest point at the bulb measures about .7” so most standard test jars will suit taking your readings. 

We offer other Herculometers to zoom-in on different gravities:


Made of extremely durable polycarbonate plastic, the Herculometer™ hydrometer will survive the strongest/clumsiest of homebrewing men and women. With a specific gravity (SG) range of 0.982 to 1.160 and a triple scale format, you’ll be able to measure for beer, wine and even meads.
