Description

A calculator to determine hydrometer adjustments based on temperature.  When you take a hydrometer reading at a temperature different than the calibration temperature small errors are introduced.  While the error is small at room temperature, it can be large at high brewing temperatures or low fermenting temperatures.

Use

bulletSelect the Hydrometer Adjust command on the Tools menu.
bulletEnter the measured specific gravity and temperature.
bulletIf needed, enter your hydrometer calibration temperature.
bulletRead the corrected specific gravity.

View Description

bulletMeasured Specific Gravity - The specific gravity measured by the hydrometer.
bulletTemperature - The temperature that the measurement was taken at.  In most cases this is the temperature of the wort.
bulletCorrected Specific Gravity - The adjusted specific gravity, with a correction made for temperature.
bulletCalibration Temperature - The calibration temperature of the hydrometer.  This is the temperature at which the hydrometer requires zero adjustment.  The instructions with your hydrometer list the calibration temperature.  Most common beer hydrometers are calibrated to 60 degrees F or 15C.  Some laboratory hydrometers are calibrated to 68F.
