Abstract
A digital thermometer, having a sensing tip that is integral with a heater, a display, and a microcontroller 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.
