A Comprehensive Guide to Types of Thermometers and How to Use Them
Posted by Yogesh Nadar on
Thermometers are essential in measuring body temperature in both healthcare and everyday life. This small but indispensable instrument correctly detects the presence of fever and other health irregularities. In this detailed blog, we will look at numerous types of thermometers, their applications, and the step-by-step technique of using them successfully.
The Different Types of Thermometers
1. Digital Thermometers:
Digital thermometers have become the standard for temperature measuring due to their precision and ease of use. These thermometers use electronic sensors to detect temperature and deliver a digital measurement. They are available in various forms, including oral, rectal, and infrared variations.
2. Infrared Thermometers:
Infrared thermometers, often known as non-contact thermometers, have grown in popularity due to their ability to monitor temperature without physical contact. These thermometers provide rapid and hygienic temperature readings by catching the infrared radiation generated by the body.
3. Mercury Thermometers:
Although less prevalent due to environmental concerns, mercury thermometers are noteworthy for their precision. Traditional thermometers use the expansion of mercury to detect temperature. However, they should be handled with caution because of mercury's toxicity.
4. Ear (Tympanic) Thermometers:
Ear thermometers are used to measure the infrared radiation emitted by the eardrum. They are quick and accurate, making them ideal for newborns and young toddlers.
5. Temporal Artery Thermometers:
Temporal artery thermometers employ infrared technology to monitor the temperature of the blood flowing through the temporal artery on the forehead. They are non-invasive and provide immediate results, making them suitable for people of all ages.
How to Use a Thermometer
Now that we've looked at the different types of thermometers let's go over how to use a thermometer step by step:
1. Digital Thermometers:
● Oral Use:
- Place the thermometer beneath the tongue.
- Keep your mouth closed and breathe properly.
- Wait for the beep or the time indicated on the thermometer.
- Make a note of the temperature.
● Rectal Use:
- Lubricate the thermometer's tip with a water-based lubricant.
- Carefully insert the thermometer into the rectum.
- Wait for the beep or the indicated time.
- After using the thermometer, properly clean it.
2. Infrared Thermometers:
- Point the thermometer towards the required place (forehead, ear, or other body parts).
- Press the button to start the temperature measurement.
- Wait for the reading to appear on the display.
3. Mercury Thermometers:
- Shake down the mercury to the bulb end of the thermometer.
- Place the thermometer under the tongue or in the armpit.
- Wait a few minutes for the mercury to settle.
- Take the temperature at eye level.
4. Ear (Tympanic) Thermometers:
- Check for any blockages in the ear canal.
- Carefully insert the thermometer into the ear canal.
- Press the button to begin the measurement.
- Take note of the indicated temperature.
5. Temporal Artery Thermometers:
- Gently swipe the thermometer across the brow.
- Maintain proper skin contact.
- Press the button to begin the measurement.
- Take note of the indicated temperature.
Uses & Advantages of Thermometer
The functions of thermometers go beyond simply checking for fever. They are indispensable in a variety of situations, including:

Factors to Consider When Purchasing a Thermometer
A thermometer's price varies depending on the type and brand. Digital thermometers are typically less expensive; however, infrared thermometers may be more expensive due to their advanced technology. When purchasing a thermometer, consider the accuracy, convenience of use, and cleanliness factors.
Thermometers are an important piece of medical equipment in hospitals. Their presence in numerous departments, from paediatrics to emergency rooms, emphasises their importance in patient care. Hospitals invest in high-quality thermometers to ensure precise and dependable temperature measures for medical diagnostics and monitoring.
Finally, thermometers are essential medical equipment in both healthcare. Individuals may monitor their health and help with the early diagnosis of illnesses by understanding the many types of thermometers and how to use them properly. Thermometers' precision, portability, and advantages make them invaluable assets in medical settings, companies, and households. As technology advances, the role of thermometers in assuring health and safety remains critical.
FAQs: Thermometer Uses
What are the main types of thermometers available in the market?
There are several types of thermometers, each serving specific purposes. The main types include digital thermometers (oral and rectal variants), infrared thermometers, mercury thermometers (less common due to environmental concerns), ear (tympanic) thermometers, and temporal artery thermometers. Digital and infrared thermometers are widely used for their accuracy and convenience.
How do I properly use an infrared thermometer to measure body temperature?
Using an infrared thermometer is simple and non-invasive. Point the thermometer at the desired area (forehead, ear, or body part), press the button to initiate the measurement, and wait for the reading to appear on the display. Ensure good contact with the skin for accurate results. It's essential to follow the manufacturer's instructions for specific guidelines on usage.
Are there any advantages to using digital thermometers over traditional mercury thermometers?
Yes, digital thermometer uses over traditional mercury thermometers. Digital thermometers provide quick and precise temperature readings, are user-friendly, and eliminate the risk of mercury exposure. They are also available in various forms, such as oral and rectal variants, making them versatile for different age groups. Mercury thermometers, while accurate, have become less common due to environmental concerns and the availability of safer alternatives.
