Abstract: A food safety thermometer is provided that measures the temperature of a food item and notifies the user when the food item has maintained a preselected temperature for a predetermined amount of time.

Abstract: 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.

Abstract: A timer for a time measurement device includes a display field that displays measured time in a first set of time units, e.g., hours/minutes. The display also includes a user activated input device for toggling the displayed time to a second set of time units, e.g., minutes/seconds.
