Abstract
A self-calibrating temperature sensing probe having a temperature sensor positioned adjacent to a vial of a predetermined substance in an isothermal environment created by a housing and insulation. A heating element is positioned about the vial to effect vial heating. The substance is preselected for its melting point temperature, which is in excess of the ambient temperature of the environment surrounding the housing. During recalibration the substance is heated above its melting point and allowed to cool. During cooling the temperature of the substance is recorded and the liquid-to-solid phase change determined. Recalibration is affected using the phase change temperature of the substance as a calibration point.
