HYD04 hydrometer jar is a plastic cylinder used for specific gravity measurement of Dynalene glycol and HC products. These unbreakable jars are used to hold the test fluid while measurement using HYD01 propylene glycol (0.990 to 1.050), HYD02 ethylene glycol (1.000 to 1.220) and HYD03 Dynalene HC (1.000 to 1.600) hydrometer.
A hydrometer is a tool to measure the specific gravity of liquids. Specific gravity is the ratio of the mass of a liquid to the mass of an equal volume of distilled water. Because the density of a liquid changes with temperature, hydrometers are calibrated for different reference and sample temperatures. Classically, the specific gravity was measured using the density of water at 4°C (39.2°F) which is the temperature of maximum density of pure water. Today, most hydrometers used in water quality testing are calibrated for with a reference temperature of 15.5°C (60°F). Because specific gravity measures the mass of a liquid over the mass of distilled water, specific gravity is unitless.
