Abstract: A method of testing for a desired specific gravity of a liquid. The method including the use of a temperature calibration gauge and a hydrometer. The temperature calibration gauge has a thermo sensing end and a readout indicating the desired hydrometer reading at the current temperature of the liquid. The method includes the steps of contacting the thermo sensing end and the hydrometer with the liquid and comparing the readout of the temperature calibration gauge with the measurement indicated by the hydrometer.

Abstract: A liquid density measuring device for use with a hydrometer comprising a vessel for receiving a liquid sample with a temperature calibration gauge having a thermo sensing end in contact with the liquid sample within the vessel. The gauge including a readout can be either analog or digital. The readout indicates a number relative to a current temperature of the liquid sample as sensed by the gauge. The number indicated on the readout being a desired hydrometer reading at the current temperature of the liquid sample. The readout will change to indicate a different desired hydrometer reading if the liquid sample changes temperature.
