These ultra precision specific gravity hydrometers measure the ratio of the mass of a solid or liquid to the mass of an equal volume of distilled water.

These precision short form specific gravity hydrometers use less volume of the test liquid while still offering 0.001 resolution.

These specific gravity hydrometers feature an internal thermometer for calculating temperature corrections and are calibrated for use at 60 ℉.

These precision specific gravity hydrometers measure the ratio of the mass of a solid or liquid to the mass of an equal volume of distilled water.

Dual-Scale Hydrometers have two scales on the stem, covering different applications in one unit.

These wide range specific gravity hydrometers are ideal to use when you aren't sure of the approximate value of your liquid. These refractometers can also be used for measuring multiple liquids with different specific gravity amounts.

This dual scale hydrometer measures the specific gravity and baume of liquids.

Our battery acid hydrometer set is used in many industrial settings including fleet maintenance, automotive services, solar-powered system maintenance, and general industrial applications.

VEE GEE scientific Baume scale hydrometers are for liquids heavier than water. The Baume scale is based on the following: Specific gravity = 145/(145 - degrees Baume).

These hydrometers measure the percentage of sodium chloride. Specifically, model 6611-1 measures the saturation percentage of sodium chloride in solutions and model 6611-2 measures the percentage by weight of sodium chloride in solutions.

This calcium chloride (CaCl₂) hydrometer measures the specific gravity and freezing point of calcium chloride in solutions.

Our alcohol hydrometers measure using the tralle and proof scales.

These IRS alcohol hydrometers use the proof scale and comply with IRS specifications.

These IRS alcohol hydrometers use the Proof scale and comply with IRS specifications.

Our Plato hydrometers are calibrated to show the concentration of extract as a percentage by weight in brewery wort. For example, a 5° P reading indicates 5 g of extract per 100 g of wort.

These liquid petroleum gas (LPG) hydrometer measures the specific gravity of LPG such as propane, butane, and other light hydrocarbons.
