Specific Gravity Hydrometers with Thermometer

VEE GEE Scientific Precision Specific Gravity Hydrometers feature an internal thermometer for calculating temperature corrections if your fluid temperature varies from 60°F. 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.
Items 6602TS-7 and 6602TS-8 have an approximate length of 385 mm and 0.001 subdivisions; item 6603TS-1 has an approximate length of 305 mm and 0.002 subdivisions.
