A food safety thermometer is provided that is easily calibratable. The thermometer includes a digital display for displaying the temperature of food items under measurement. A calibration unit is coupled to the digital display. The calibration unit generates a calibration alert when the measured temperature is maintained within a calibration range for a predetermined period of time (the calibration period). If the user elects to calibrate the thermometer during the calibration period, the may activate the calibration unit and the calibration unit drives the measured temperature to the calibration temperature.

1. A calibratable food safety thermometer comprising:a probe including a distal end and a proximal end, the proximal end including a temperature sensing device; a digital display in communication with said temperature sensing device that displays a temperature of the food item sensed by the temperature sensing device; and a calibration unit in communication with said digital display that a) provides a calibration alert for a calibration period when the temperature sensing element measures a temperature within a calibration temperature range, b) drives the digital display to a calibration temperature responsive to an activation signal received during the calibration period, and c) causes digital display to display the temperature sensed by the temperature sensing device after the calibration period in the absence of reception of the activation signal during the calibration period. 2. The calibratable food safety thermometer of claim 1 wherein the calibration period has a duration of at least 3 seconds.3. The calibratable food safety thermometer of claim 2 wherein the calibration alert has a duration of between 4 and 8 seconds.4. The calibratable food safety thermometer of claim 1 wherein said calibration unit includes a user selectable calibration temperature.5.
