Infrared thermometers are designed to measure the temperature of an object, surface, or substance without physically touching it.

Infrared thermometers are used primarily for non-contact temperature measurements of objects in industrial processes, quality control, or building maintenance.

A small amount of infrared light is emitted from a hot object. This infrared light is then detected by the infrared thermometer. The infrared thermometer converts the detected infrared light into a temperature reading, which is displayed in units of temperature. For more accurate readings, the infrared thermometer can also use a lens to magnify the infrared light produced by the hot object.


An infrared thermometer, also known as a pyrometer, measures infrared radiation from objects in their field of view. Infrared thermometers operate in the 3 to 5 µm wavelength range, invisible to the human eye. In the IR range, there is little difference between objects of different temperatures. The temperature of an object is an average of the object’s temperature in the direction of the thermometer and its temperature in the opposite direction. The temperature of an object is proportional to the intensity of the IR radiation it emits.

An infrared thermometer is one of the most useful gadgets you can have in your home. It measures the temperature of objects by aiming a laser infrared beam at the object in question. The beam is invisible to the naked eye, which makes it easier to aim. The laser beam will penetrate the surface, and some of the infrared radiation will reflect back to the thermometer to be analyzed. The temperature of the object it is aimed at will be displayed.

So you’ve decided to buy an infrared thermometer. If you’re like most, you’ve probably already realized that there are a lot of infrared thermometers on the market. This can make it hard to decide which infrared thermometer is right for you. Will you use it at home? On the job? Hunting? Fishing? Camping? Or maybe you’re like some of us and will use it for all of these things and more.

Are infrared thermometers accurate?

Although infrared thermometers may seem like a relatively new technology, they have actually been around for a couple of decades. However, they have only become a mainstream product over the past year, and are now being marketed to homeowners as a way to quickly measure the temperature of their home. However, there have been claims that these thermometers are not as accurate as they appear to be. Infrared thermometers are helpful for getting an idea of the temperature in a particular area, but they’re not necessarily very accurate.

Can you take body temperature with infrared thermometer?

infrared thermometers

An infrared thermometer can measure the temperature of an object without actually touching it. These thermometers are handy around the kitchen or in the garage for checking the temperature of food or engine blocks and can save you from getting dirty when working around the house. (Ew! Who wants to measure the oven temperature and then get your hand all greasy?)

First, it’s important to understand that infrared body temperature measurements are simply estimates — not definitive readings. Infrared thermometers are designed to measure surface temperatures, not the temperature inside the body. So, if you use an infrared thermometer to measure your temperature, it will probably be more than a degree or two off the mark.

What is normal body temperature using infrared thermometer?


The normal body temperature for humans is 37 degrees Celsius (98.6 degrees Fahrenheit). This is normally taken as the temperature of a person’s skin, although it can also be measured inside the mouth. To measure the temperature of a person’s skin, you need an infrared thermometer. You can measure the temperature of a person’s internal organs as well, although we will concentrate on measuring the temperature of the skin in this article.

How do I check my temperature with an infrared thermometer?

So you’re looking for a quick and easy way to check the temperature of your home for any problems? If so, you may be interested in infrared thermometers. These devices can be used to check the temperature of your home to ensure that it is as comfortable as possible. They’re particularly useful for checking your home’s temperature without having to be there in person.

Is it safe to use infrared thermometer on forehead?

Since infrared thermometer could only measure surface temperature while you need to know body temperature for a more accurate result, I think it could be okay to use infrared thermometer on forehead. But, why not to use infrared thermometer to measure body temperature?

Bottom line

So, overall, the bottom line is that an infrared thermometer can be a great tool in your home, provided you use it appropriately. You can use it for cooking, keeping your pets comfortable, as well as for a variety of other applications, like checking for air leaks or even when installing insulation. The key is to use it appropriately in order to get accurate readings and to avoid any potential safety hazards.
