How Does A Digital Thermometer Work?

Digital thermometers have sensors that make them quick and automatic at displaying accurate temperature. These sensors are designed to detect a change in temperature through voltage, current, and resistance. In easier terms, when the thermometer detects a change in temperature as you place it in your mouth or any other part of your body, it creates current proportional to the temperature and gives you a reading.

Expert’s Answers For Readers’ Questions

Are digital thermometer readings accurate?

Yes, digital thermometers are accurate. If you recognize a temperature variation between a contact and non-contact thermometer, it’s probably because of the extreme surrounding temperature or the distance between the non-contact thermometer and the forehead.

How long do you take your temperature with a digital thermometer?

It takes between 1-30 seconds to take a temperature reading. Most of the non-contact digital thermometers take just 1 second to give out the reading.

How do I know if my digital thermometer is working?

Most of the digital thermometers display the minimum temperature it can read or ‘LO’ before it starts reading your body temperature. Please note that the ‘LO’ denotes low body temperature and not low battery level of your thermometer. If you can see this on the display after you turn it on, your thermometer is working.

How often should I clean the thermometer and how?

A contact thermometer must be cleaned after each use to ensure hygiene.

Can we wash a digital thermometer?

Digital thermometers can be washed. Washing the tip with lukewarm water and soap will make it safe to be reused.

What are the disadvantages of a digital thermometer?

Digital thermometers run on batteries and might need a battery replacement.
