Infrared thermometers (also known as forehead thermometers, touchless thermometers or temporal artery thermometers) measure temperature by tracking the level of thermal and infrared radiation being emitted from arteries and blood vessels in the head.
You can take readings one of three ways, depending on the style of thermometer:
Taking a heat reading this way means that these thermometers do not need to be in extended contact with the patient.
There are two main types of infrared thermometers available:
Infrared thermometers can also refer to laser thermometers or temperature guns, which are often used for industrial purposes or in cooking. They all operate using similar technology, but lasers and guns are bigger, more expensive pieces of equipment.

Basic thermometers start at around $10, while more advanced models can cost $100 or more. When deciding which thermometer to buy, you'll need to consider the following:
Thermometers typically state a temperature range they can measure. Most have a range of around 10 degrees, usually somewhere between 32 and 44 degrees. Some thermometers also take the temperature of bath water and milk, and may offer readings between 0 and 100 degrees.
How does the thermometer feel in your hand? Does it have a backlit display? Does it colour code readings to show a fever? Thermometers come in a range of designs. While bells and whistles don't necessarily make for a better product, you'll want to feel comfortable using it.
Some thermometers offer storage space and the ability to recall previous readings. This allows you to track someone's temperature over a period of time, and note any fluctuations.
Battery types for thermometers include AAA, AA and button batteries. If you have small children, you might want to consider avoiding button batteries as they can be attractive, shiny and easily swallowed.
