Final answer:
Hand-held digital thermometers are quicker and more convenient to use than traditional thermometers and require yearly calibration. They use a thermistor to measure temperature and provide faster and more accurate temperature readings.
Step-by-step explanation:
The hand-held digital thermometers are quicker and more convenient to use than traditional thermometers and require yearly calibration.
Digital thermometers use a thermistor to measure temperature. A thermistor is a temperature-sensitive resistor that changes its resistance with temperature. The change in resistance is then converted into a temperature reading on the screen.
Unlike traditional thermometers, digital thermometers provide faster and more accurate temperature readings, making them highly convenient for everyday use.
