VEE GEE Hydrometers are manufactured to exacting standards. Each in-strument is individually tested and inspected to insure the highest level of dependability, accuracy, and uniformity.

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 liquids heavier than water and for liquids lighter than water. The base hydrometer scale is Specific Gravity, in which distilled water equals 1.000 as the initial point. Liquids lighter than water are scaled below 1.000 specific gravity and liquids heavier than water are scaled above 1.000 specific gravity.

Many other scales are commonly used, such as API, Brix, Baume, Plato, etc. All of which are convertible into specific gravity by formula.

Hydrometers are usually calibrated at 60°F/60°F. To determine the density of a liquid, the liquid should be at 60°F. If the temperature varies, the liquid will either contract or expand, depending upon the temperature. Therefore, the density fluctuates with the temperature. Where there is a variation from the standard 60°F, corrections must be applied to the hydrometer reading. To assure proper corrections, a separate accurate thermometer should be used, or a hydrometer in combination with a thermometer, which is sometimes referred to as a “thermohydrometer.”

The correct method of reading a hydrometer follows:

If the liquid is not sufficiently clear for readings to be made in this manner, read from above the surface and estimate as accurately as possible the point to which the liquid rises on the hydrometer stem. Since hydrometers are calibrated to give correct indications when read at the principal surface of the liquid, correct the reading just taken at the upper edge of the meniscus by an amount equal to this height above the principal surface of the liquid. The amount of correction can be determined with the sufficient accuracy for most purposes by taking a few readings on the upper and lower meniscus in a clear liquid of the same character as that being tested and noting the differences.

- 131.5

The API Scale was selected in 1921 by the American Petroleum Institute (API), the U.S. Bureau of Mines, and the National Institute of Standards and Technology (NIST) as the standard hydrometer scale for petroleum products. The API Scale is based on the following formula:

The thermometer scale for VEE GEEHydrometers (w/ Thermometers) is located in the body. A correction scale for conversion of readings to 60°F is printed opposite the temperature scale.

General Specifications for VEE GEE ASTM Hydrometers: Manufactured in strict accordance to specifications of ASTM (American Society for Testing and Materials) for accuracy and design. All instruments are suitable for certification for use as a primary reference standard with NIST traceability.

Specific Gravity, also known as relative density, is the ratio of the mass of a solid or liquid to the mass of an equal volume of distilled water. The standard temperature of calibration in the U.S. is 60°F/60°F. All VEE GEE Specific Gravity Hydrometers listed are calibrated at 60°F/60°F.

The thermometer scale for VEE GEE Hydrometers (w/ Thermometers) is located in the body. A correction scale for conversion of readings to 60°F is printed opposite the temperature scale.

Brix

VEE GEE Brix Hydrometers are calibrated to show the percentage of sucrose by weight at 20°C. The Brix Scale is based on the following: 1° Brix = 1% sucrose by weight at specificed temperature (20°C). The data of the National Bureau of Standards are used.

The thermometer scale for VEE GEE Hydrometers (w/ Thermometers) is located in the body. The thermometers have a range of 0 to +50°C or +30 to 150°F with 1° subdivisions. A correction scale for conversion of readings to 20°C or 68°F is printed opposite the temperature scale.
