Shopping for a contactless infrared thermometer?
You’ve come to the right place.
Infrared thermometers, also called non-contact thermometers or thermal guns, are used to measure the temperature of different surfaces from a distance.
An infrared thermometer collects thermal radiation (black body radiation) emitted by an object.
A lens focuses the radiation on a detector that turns the infrared radiation into an electric signal. A sensor uses the electrical signal to determine the temperature of the target object.
An infrared thermometer is useful in circumstances where a contact temperature probe cannot be used because either it’s dangerous to get too close to the surface or the expected temperature exceeds the recommended maximum for a contact thermometer.
For example, you can use an IR thermometer to measure a very hot surface like an oven, grill, or a car engine.An IR thermometer is also handy for measuring human temperature without coming into contact with a person.
What's in This Guide?
In this buying guide, we review and compare the best contactless IR thermometers & thermal guns.
Types of Infrared Thermometers
Spot infrared thermometers: These are the most common types of IR thermometers. They are used to measure the temperature of an object at a spot. The accuracy of these thermometers is greatly determined by the D:S or distance-to-spot ratio. The higher the D:S ratio, the more accurate the thermometer.
Infrared scanning systems: These are used to scan over a wider area. They are mostly used during manufacturing.Thermal imaging cameras: Thermal cameras work like infrared thermometers, taking infrared light and using it to determine an object’s temperature.
The main difference is that a thermal camera detects the temperature of multiple spots over a wide area and then creates a thermal image called a thermogram.
Different colors on the image indicate how hot or cold a particular spot.

Buying Guide: How to Choose An IR Thermometer
Here are the most important factors to consider when you are shopping for an infrared thermometer.
What are non-contact thermometers, and how do they work?
Non-contact infrared thermometers or temperature guns are non-invasive tools for checking the temperature.
They are used to monitor the temperature of extremely hot or dangerous-to-touch objects.
Infrared thermometers use radiations to assess the object’s temperature. Objects release different kinds of electromagnetic radiation at different temperatures.
The lens in the infrared thermometer picks out the specific radiation that an object emits.
Then the lens focuses this radiation on a sensor called thermopile that converts electromagnetic radiation into electricity.
Lastly, another sensor picks up this electricity and converts it into a suitable temperature reading.
Different Applications of Infrared Thermometers
Infrared thermometers serve many purposes in home and in commercial settings, for example:
Cooking is highly dependent on maintaining the right temperature. An IR thermometer helps you determine the temperature of your grill or stovetop without touching it. This helps avoid overcooking or undercooking food, particularly meat.
IR thermometers are used extensively in medical settings. They help monitor the temperature of patients with contagious diseases, for example.
Infrared thermometers are also reliable for checking the body temperature of animals who keep moving.
Mechanics use infrared thermometers to check the temperature of radiators and other vehicle parts.
Automotive experts rely on non-contact IR thermometers to troubleshoot overheating issues in vehicles. These thermometers are reliable when it comes to checking brakes and tires.
Heating, ventilation, and air conditioning experts need to check for leaks and issues in ducting, plumbing, and electrical systems.
IR thermometers make it easy to identify them by detecting abnormal temperature differences caused by air duct leaks, water leaks, and shorts in the wiring.
Food workers and manufacturers widely use IR thermometers to ensure food products are maintained at a safe temperature.
Infrared thermometers are used in many kinds of industrial settings, for example, in manufacturing to inspect products and work-in-process for faults, electrical shorts, leaky hoses, and many other defects.
In chemical processing, IR thermometers are used throughout processing plants in many different ways.
Temperature audits are also useful in product warranty repairs.
IR thermometers are helpful for troubleshooting issues with electrical circuits.
Electricians often carry IR thermometers and imagers with them to ensure there are no issues with the electrical wiring and circuits.
What to Consider When Choosing the Best Infrared Thermometer
Distance to Spot Ratio
The distance-to-spot ratio tells you how accurate the thermometer is. The typical D/S ratio is 12:1, meaning you can measure a 1" wide spot from 12" away.
A lower D/S ratio means you have to get closer to the target to get an accurate reading, which can be a problem when measuring very hot surfaces.
A higher D/S ratio is generally better as it gets you more accurate measurements and allows you to stay a safe distance from a potentially dangerous surface. However, if you don't plan to measure extremely hot surfaces, don't pay for a higher D/S ratio. For most situations, a 12:1 IR thermometer is adequate.
Accuracy is a major concern when it comes to buying an infrared thermometer. Manufacturers mention the thermometer’s accuracy in plus and minus values.
Most IR thermometers have an accuracy of +/- 2%, which is fine for most uses. You can also find professional IR thermometers with +/- 1% accuracy, but they are more expensive.
The best temperature range depends on your particular situation. If you often measure extra-hot or extra-cold surfaces, look for an IR thermometer with a wide range.
Some IR thermometers measure only up to around 700F max and -30F min. Others can measure temperatures higher than 2,000F and as low as -58F.
An object's emissivity refers to its effectiveness in emitting thermal radiation. For instance, the emissivity of human skin is about 0.98, while that of aluminum foil is 0.03.
You can have two different surfaces at the same temperature but get two varying readings with an IR thermometer because of the difference in emissivity.
For accurate readings, it's important to get an IR thermometer with adjustable emissivity. This lets you adjust the setting as you measure different surfaces.
Look for an IR thermometer with a large and backlit display. A backlit display lets you measure temperature even in dark areas.
Hold: Holds temperature reading on the screen to give you time to read and record it.
Min and max: Records the highest and lowest temperatures recorded from an area.
Memory: If you'd like to store readings for recording or analysis, look for an IR thermometer with internal memory.
If you work in outdoor or harsh environments, look for an IR thermometer with a weather-resistant and hardy construction. Ideally, it should have some dust and moisture protection.
If the thermometer doesn't come with a case, make sure you get one, preferably a hard case.
Pros and Cons of Infrared Thermometers
Cleaning and Maintaining Your Infrared Thermometer
Cleaning and maintaining your infrared thermometer regularly is essential for accurate temperature readings. Dust, grime, and debris accumulation will affect the accuracy of your unit.
To clean your IR thermometer:
Store the thermometer in a clean and dry place when it is not in use.
Most IR thermometers work best when stored at a temperature of 40°F to 100°F. Avoid storing them in more extreme temperatures for extended periods of time.
