When someone is ill, guesswork is the last thing you want to rely on. So, keeping a trustworthy digital thermometer at home can be really beneficial. Knowing for sure if someone is feverish gives you crucial information regarding the next actions for their care.

There are numerous varieties of both contact and contact-free digital thermometers. You can choose which sorts to purchase based on your personal preferences and the ages of the people in your household.

It’s crucial to comprehend how your thermometer functions, just like any other appliance in your house.

Here we are going to provide an explanation of digital thermometer uses, their types, and how to use them. 

What is a digital thermometer?

A tool for measuring temperature is a digital thermometer. This kind of thermometer measures body temperature using heat sensors. You can use it to measure the temperature in your mouth, rectus, or armpit.

How does digital thermometer work?

Due to the simplicity of getting readings, digital thermometers are gradually replacing the traditional mercury thermometer. People frequently believe that it includes mercury. But digital thermometers don’t contain any mercury.

The thermistor inside the tip of these thermometers is used to gauge the temperature. An electrical current flows through the thermoresistor, and the resistance, or how easily the current may pass, varies with temperature. A little computer or other circuit calculates the temperature by measuring the resistance.

Digital ear (tympanic) thermometer

Tympanic thermometers use infrared technology to gauge the ear canal’s temperature. Oral temperature readings are typically within 0.5°F (0.3°C) to 1°F (0.6°C) of tympanic readings. 

Digital Forehead (temporal) thermometer

A forehead thermometer measures the temperature of the superficial temporal artery, a branch of the carotid artery, using infrared sensors. Some are referred to as infrared thermometers without contact.

The use of forehead thermometers in places like stadiums, shops, and airports has grown in popularity during COVID-19. These thermometers don’t require any physical contact.

Oral temperature readings are typically about 1°F (0.6°C) warmer than forehead values.

  • The LCD displays on these thermometers make them simple to read.
  • They can record a wide range of temperatures and have a beep alarm and memory feature.

Disadvantages: 

  • The device’s tip should be kept under the tongue with the mouth completely closed in order to obtain an accurate reading when used orally.
  • If oral readings are examined too soon after a person consumes hot food or drink, the findings may be influenced by the temperature of the meal or drink.
  • Rectal reading may be challenging for infants and young children to handle.

Digital ear thermometer benefits & drawbacks

Advantages: 

In comparison to oral or rectal thermometers, tympanic thermometers offer quick and precise readings and may be preferred, particularly in children. 

Disadvantages: 

  • Tympanic thermometers are not advised for newborns under 6 months old due to the size of the ear canal.
  • To obtain accurate results, they must be positioned correctly.
  • Earwax obstructions might cause results to be off.
