How to Choose the Right Thermometer for Your Needs

Your Guide to buying the best Thermometer


This buying guide provides an overview of the different types of thermometers available and the key considerations to make when shopping for one. We will discuss the different features of thermometers and the best ways to measure temperature. We will also consider the different uses and benefits of thermometers, so you can make an informed decision about the best thermometer for your needs.

Key features

  • Type: The type of thermometer you need will depend on your needs. Some thermometers measure temperature in a specific area, such as in the ear, on the forehead, or in the mouth. Other thermometers measure temperature in a larger area, such as a room or a building.
  • Accuracy: The accuracy of the thermometer is an important feature to consider. Make sure you know how accurate the thermometer is and what range of temperatures it’s able to measure.
  • Durability: Choose a thermometer that is made of durable materials that will last you for years.
  • Ease of Use: Choose a thermometer that is easy to use. Look for thermometers that have simple buttons and displays that are easy to read.
  • Cost: Thermometers vary in price, so consider how much you are willing to spend on one.
  • Size: Take into account how much space you have available for the thermometer and choose a thermometer accordingly.
  • Thermometer Display: Choose a thermometer that displays the temperature in a format that’s easy for you to read and understand.

Important considerations


  • Accuracy: Thermometers are designed to measure temperatures accurately and consistently.
  • Versatility: Thermometers can be used for a variety of tasks, from taking a person’s temperature to monitoring the temperature of food and liquids.
  • Durability: Thermometers are generally durable and can last for years with proper care.
  • Ease of Use: Most thermometers are relatively easy to use and require minimal setup.
  • Cost: Thermometers can range in price, making them more affordable for those on a budget.
  • Safety: Thermometers are designed to take accurate readings without hurting the user.


  • Cost - Thermometers can range in price considerably, depending on the type, accuracy, and features of the model. More expensive thermometers tend to be more accurate and have more features, but may not be necessary for most consumers.
  • Accuracy - Not all thermometers are created equal and some may be more accurate than others. Inexpensive models may not provide accurate readings and could be inaccurate by several degrees.
  • Maintenance - Some thermometers may require periodic maintenance, such as battery replacement, recalibration, or cleaning. This may add to the cost of owning a thermometer.
  • Durability - Thermometers can be sensitive to extreme temperatures or shocks. Cheaper thermometers may not be as durable and may not last as long as more expensive models.

Common questions

  1. What type of thermometers are available? There are several types of thermometers available, including digital, infrared, and mercury thermometers. Digital thermometers are the most common and are available in a variety of styles, including ones with an LCD screen or ones with a probe. Infrared thermometers measure temperature via a non-contact infrared beam, and are commonly used to measure the temperature of liquids and surfaces. Mercury thermometers are non-electronic and use a mercury column to measure temperature.
  2. What are the advantages and disadvantages of each type of thermometer? Digital thermometers are the most accurate and are generally the most convenient to use, as they are easy to read and often have additional features such as memory or alarms. Infrared thermometers are non-contact and are useful for measuring surface temperatures without coming into contact with the object. However, they are more expensive and can be less accurate than digital thermometers. Mercury thermometers are the least expensive and are useful for measuring temperatures over long periods of time, as the mercury column can be seen to slowly rise or fall. However, they are less accurate than digital thermometers and can be difficult to read.
  3. What features should I look for when buying a thermometer? When buying a thermometer, look for features such as accuracy ratings, temperature range, and additional features such as memory or alarms. Additionally, you may want to consider if the thermometer is waterproof or dustproof, as well as if it is battery-powered or requires a power source.


A funny fact about thermometers is that the first thermometer ever invented was inspired by a fish! In 1592, Galileo Galilei created a thermoscope, which was a simple instrument that would show changes in temperature. He was inspired by a fish that would move slower when the water got colder and faster when the water got warmer. Today, thermometers measure temperature with much more accuracy than Galileo's thermoscope, but his invention laid the foundation for modern thermometers. Source: Science ABC
