Calibrated at 60°F
Specific Gravity, also known as relative density, is the ratio of the mass of a solid or liquidto the mass of an equal volume of distilled water. The standard temperature of calibrationin the U .S. is 60°F/ 60°F. All Bellwether Specific Gravity Hydrometers listed are calibratedat 60°F/ 60°F.
