Why Should The Electronic Thermometer Add 0.5 Celsius?
- Aug 27, 2018 -

Electronic thermometers generally have a beep sound after the measurement is finished. If the thermometer is taken out, the temperature will be low, so add about 0.5. If the measurement is finished after the buzzer is not taken out for another 2 to 5 minutes, then the temperature displayed at this time is similar to the body temperature, and it is not necessary to add it.


Because the thermometer temperature rises slowly, and the thermometer is based on how many seconds after the temperature is constant, the buzzer measurement ends, and the temperature will rise if the thermometer is not taken out.


The electronic thermometer uses the temperature sensor to output an electrical signal, directly outputs a digital signal or converts the current signal (analog signal) into a digital signal that can be recognized by an integrated circuit, and then passes through a display (such as a liquid crystal, a digital tube, an LED matrix, etc.). The temperature in digital form is displayed, and the highest value of the measured temperature can be recorded and read.


The core component of an electronic thermometer is the NTC temperature sensor that senses temperature. The resolution of the sensor is up to ±0.01 °C, the accuracy is up to ±0.02 °C, the reaction speed is 2.8 seconds, and the annual resistance drift is ≤0.1% (equivalent to less than 0.025 °C).
