Answer:
Digital electronic thermometers measure temperatures with a heat sensor and require a button battery. They measure temperatures quickly, usually in less than 30 seconds. The temperature is displayed in numbers on a small screen. The same thermometer can be used to take rectal, armpit, and oral temperatures

Answer:
A digital thermometer do not take more than 1 minute to get a reading. We have to place the thermometer under the side of the tounge or at under arms until the thermometer beeps. When it beeps it means that it has checked the temperature and we can read the reading of the body temperature.
