Overview
        The hydrometer is an instrument which is constructed on the Archimedes principle that a solid body displaces its own weight of the liquid in which it floats. Hydrometers can be divided into two general classes; namely for liquid heavier than water and for liquids lighter than water.
Alcohol Hydrometers - Tralle and Proof Scales - 
Verify the alcohol content of distilled spirits
Both models include the same ranges; model 6612-2TS also features an internal thermometer with SafetyBLUE
fill for measuring solution temperature from -10 to +100°F.
- Calibrated for use at 15°C/60°F
Alcohol Hydrometers - Proof Scale, Internal Revenue Service Spec-
Verify the alcohol content of your ethyl alcohol-based spirits with these hydrometers
- Tolerances match those laid out by the Internal Revenue Service specifications
- Calibrated for use at 15°C/60°F
Alcohol Hydrometers w/3-point NIST Certificate and PVC Case- Proof Scale, Internal Revenue Service Specification-
Verify the alcohol content of your ethyl alcohol-based spirits with these hydrometers
Tolerances match those laid out by the Internal Revenue Service specifications.
- Commonly used in distilleries requiring certification
- Calibrated for use at 15°C/60°F
INCLUDES: Hydrometer, NIST-traceable certificate with 3 data points, and a protective PVC case
