An integrated standardized digital precision thermometer has a sheath (14) including a temperature sensing element (16) and a handle (12) physically interconnected with the sheath (14) and housing an integrated digital standardized thermometer circuit (26), including an analog to digital converter (30) responsive to the temperature sensing element (16) for converting an analog signal representative of the resistance of the sensing element (16) to a digital signal representative of the resistance of the sensing element (16); and a microcomputer (28) responsive to the digital signal representative of the resistance of the sensing element (16) for converting the digital signal representative of the resistance of the sensing element (16) to a standardized temperature scale (219).
