PURPOSE: A digital thermometer is provided, which is an accurate, low-cost, digital thermometer that is easy to use, further provides a peak hold temperature in a short period of time. CONSTITUTION: A digital thermometer, having a sensing tip that is integral with a heater, a display, and a micro controller which samples for rise time and proportionally operates the heater to increase the temperature of the sensing tip in an alternating control sequence that includes a post heating delay and, thus, the sensing tip quickly arrives at a stable temperature when no further heating is required.
