VEE GEE Liquid Petroleum Gas Hydrometers, Specific Gravity, with Spirit Filled Thermometer
Calibrated at 60°F The thermometer scale for Bellwether Hydrometers (w/ Thermometers) is located in the body. A correction scale for conversion of readings to 60°F is printed opposite the temperature scale. 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 Bellwether Specific Gravity Hydrometers listed are calibrated at 60°F/ 60°F. Thermometer Scale: 30 to 90°F (Subdivision: 1 °F) Specification...
