Infrared thermometers have grown in popularity over the recent past. They make it possible to measure the temperature of anything, whether it is cold water or a flaming furnace.
You can use an infrared thermometer to measure body temperature and also gauge the temperature of an oven.
Infrared thermometers work by using a laser system to detect temperature, which means you can stand at a distance from the object you want to measure and still get accurate readings.
It is no wonder then that they have quickly become must-haves for any home.

What to Consider When Selecting an Infrared Thermometer
This is the most important aspect because the whole point of a thermometer is to get accurate readings.
Infrared thermometers are used to measure temperature for professional uses e.g. in medicine, and therefore accuracy for these types of thermometers matters.
When you want to purchase an infrared thermometer, look for +-1% accuracy. Some have a +-2% accuracy, and this is also an acceptable range.
Many of the thermometers recommended on our list have a +-1% accuracy, so you can definitely trust their readings.
You might use an infrared thermometer to measure the temperature of rooms in your house during construction, the temperature of your pets, kids, or even the stove when cooking.
For this reason, your infrared thermometer should have rugged construction. It must be able to withstand to any kind of use without breaking.
Polymer material is rugged and durable. It reinforces any kind of lens and protects it from breaking easily even if the thermometer falls.
Emissivity refers to the amount of infrared energy the thermometer will release in a period of time. Since emissivity affects the accuracy of your readings, this is an important factor to consider.
Emissivity ranges from 0 to 1. An infrared thermometer with the emissivity locked at around 0.95 to 0.98 is good for general purpose use.
It is more likely than not that you will use your infrared thermometer to measure the temperature of different surfaces.
You should therefore get a thermometer with adjustable emissivity so you can adjust the scale depending on what surface or object you want to measure.
The temperature range will determine the range of objects whose temperatures you can measure.
For example, some infrared thermometers have temperature range suitable for general use like measuring body temperature and the temperature of water, but will not go high enough to measure the temperature generated by a furnace.
Infrared thermometers have the temperature range written on the body of the thermometer. The type of lens is a good indicator of the temperature range of the thermometer.
If you are likely to spend time measuring the temperature of cold objects, then a no-lens infrared thermometer will do the job.
Thermometers with Fresnel lenses will do a good job measuring medium-heat objects, while Mica lens thermometers will read very high temperatures.
This aspect ties in with the factor of accuracy. A reliable thermometer will give you accurate readings for a long period of time. You can gauge this based on the company making the thermometer.
Local companies are likely to make reliable infrared thermometers. You should make sure to check the user reviews to properly gauge the reliability of the thermometer you are interested in.
Another factor that you can use to gauge the reliability is the warranty offered.
A couple years of warranty shows that the company trusts and stands behind their product, and so you can trust this type of thermometer.
The read speed refers to the time a thermometer takes to process and display the reading. A few seconds read speed is desirable and a good indicator of accuracy and reliability.
It means you can continue with your work more efficiently, or in the case of measuring body temperature, it means you can get the help needed quicker.
If you are likely to be comparing the temperatures of different objects, then recording capabilities are an important factor to consider in your infrared thermometer.
A thermometer that can record is able to calculate the average range of temperature for a particular object and notify you of any changes in temperature over time.
A thermometer that can record the temperature will come equipped with a microSD card. The larger the capacity of the memory card, the more information it can store.
How to Use Infrared Thermometer
Infrared thermometers are versatile and can be used to take the temperature of anything, from your body to things that are too hot to be touched.
To get the most out of an infrared thermometer, you need to know how to properly use it. Before taking the temperature, make sure the thermometer is properly calibrated.
You can do this by taking the temperature of ice that has sat in a water glass for around two minutes. While the result might not be 100% accurate due to air pressure, if you are using an infrared thermometer at home this is the easiest way to calibrate your infrared thermometer.
After calibrating, you are assured of getting more accurate readings.
Here is how to take the temperature of any object using your infrared thermometer:
- Toggle between the Fahrenheit and Celsius settings to become familiar with how the thermometer works.
- Decide which temperature unit is most comfortable for you to use.
- Turn on the thermometer.
- Aim the thermometer towards the object whose temperature you want to take. Get as close as possible to the object for more accurate readings.
- Pull the trigger and read the temperature from the thermometer’s display.
An infrared thermometer is a must-have for any house. It is a versatile equipment that will serve you whether you are cooking or renovating your house, or whether you want to measure the temperature of water or body temperature.
We have reviewed 10 of the best infrared thermometers available in the market. These thermometers are high-quality and offer highly accurate and reliable readings.
Whichever thermometer you pick guarantees you a good display, a big temperature range, and even recording capabilities. Some have phone apps that enhance the read speed and recording capabilities.
You will not go wrong with the listed thermometers. So go ahead: pick one and get to measuring!
