As with all Herculometer hydrometers, this one is made with rugged polycarbonate plastic. This Precision Scale Hydrometer takes accurate readings from 1.000 to 1.070 SG.
The Herculometer is calibrated to 60°F (15.5°C).
This rugged hydrometer takes lab-accurate readings ranging from 1.000 to 1.070 SG, and is made from durable plastic rather than glass.
We offer other Herculometers to zoom-in on different gravities:
Triple Scale Hydrometer, a multi-purpose hydrometer
0.980 to 1.020 Precision Hydrometer, ideal for checking finishing gravities (FG)
1.060 to 1.130 Precision Hydrometer, for checking original gravity of big, strong beers
