Thermometers Buyer's Guide
Written by Dan GibsonIntroduction to Thermometers
Thermometers are essential tools used to measure the temperature of a variety of environments and objects. Whether you need to measure the temperature of a room, a liquid, the surface of an object, or a person, there’s a thermometer that fits your needs. In this buying guide, we’ll discuss the different types of thermometers and the features that make them unique.
Different Types of Thermometers
Thermometers come in a variety of shapes and sizes, and are designed for different uses and applications. Digital thermometers are the most popular type of thermometer, as they are accurate and easy to read. Infrared thermometers measure temperature by detecting infrared radiation, and are often used to measure the surface temperature of an object. Dial thermometers use a dial to display temperature readings, and are often used in food preparation. Glass thermometers are usually made of glass and contain a liquid that expands or contracts to display the temperature reading. Mercury thermometers are rarely used today, as they contain toxic mercury.
Features to Consider
When buying a thermometer, there are a few features to consider. Accuracy is the most important feature to consider, as you want to make sure the thermometer reads the temperature accurately. Temperature range is also important, as some thermometers are only capable of measuring a limited range of temperatures. Response time is another important factor, as this determines how quickly the thermometer can read a temperature. Some thermometers also have additional features like memory storage, backlighting, and alarms. Be sure to consider your needs when selecting a thermometer.

Digital Thermometers
Digital thermometers are the most popular type of thermometer, as they are accurate and easy to read. Digital thermometers use a digital display to show the temperature, and some models can even be connected to a computer or smartphone. Digital thermometers usually have a wide temperature range, and some models can even measure temperatures as low as -200°C. They are also fast and accurate, and can usually measure temperatures within 0.1°C of the actual temperature.
Infrared Thermometers
Infrared thermometers measure temperature by detecting infrared radiation, and are often used to measure the surface temperature of an object. They are often used in medical, industrial, and food safety applications, as they can measure temperatures from a distance. Infrared thermometers are fast and accurate, and can measure temperatures in less than a second. They are also non-contact, so they can measure temperatures without making contact with the object or surface.
Glass and Dial Thermometers
Glass thermometers are usually made of glass and contain a liquid that expands or contracts to display the temperature reading. They are often used to measure the temperature of liquids, and are usually accurate within 0.1°C. Dial thermometers use a dial to display temperature readings, and are often used in food preparation. Dial thermometers are usually accurate within 1°C and can measure temperatures up to 300°C.
