Manufactured to the Specifications of the American Society for Testing and Materials (ASTM)
Our ASTM Specific Gravity Hydrometers are calibrated at 60°F and manufactured to the specifications of the American Society for Testing and Materials (ASTM). Select the hydrometer that you need by matching the ASTM number shown. Specific Gravity, also known as relative density, is the ratio of the mass of a liquid to the mass of an equal volume of distilled water.
