Liquid Density Calibration

A hydrometer is a device that measures the specific gravity of a liquid. They can’t be adjusted, so calibration consists of determining a correction factor to apply after taking the measurement. Hydrometers are sensitive instruments and their readings are significantly affected by minor changes in the environment, especially temperature.
A hydrometer’s accuracy can be verified by measuring the specific gravity of liquids with a known temperature and composition. For example, a sample of pure water will have a specific gravity of approximately 0.998 at 20 degrees Celsius. The correction factor is calculated by subtracting the observed specific gravity from the predicted specific gravity. This correction will then be applied to any specific gravity measurements taken with the hydrometer.
