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.
Claims20
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 the temperature of the food item;
- and
- a calibration unit in communication with said digital display that provides a calibration alert when the temperature is between a first and second temperature for a predetermined period of time and that drives the digital display to a calibration temperature responsive to an activation signal.
A method of calibrating a food safety thermometer comprising:
- measuring the temperature of a calibration source;
- generating a calibration alert when the temperature of the calibration source is maintained between first and second temperatures for a calibration period;
- changing the temperature displayed by the thermometer to the calibration temperature responsive to a user input.
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 the temperature of the food item;
- a safe state alert indicator that provides a safe state alert when the temperature sensing device indicates that the food item has reached a safe state temperature and maintained the safe state temperature for a predetermined period of time;
- and
- a calibration unit in communication with said digital display that provides a calibration alert when the temperature is within a calibration temperature range for a predetermined period of time and that drives the digital display to a calibration temperature responsive to an activation signal.
