An infrared thermometer is an extremely handy tool to check temperature quickly and accurately. This non-contact temperature recording instrument is designed with smart infrared technology and highly sensitive digital sensors that accurately detect hot or cold temperatures that radiate from any surface.
Not only does an infrared thermometer detect slight changes in temperature but it displays these results on an LCD screen. Whether you use this device for the home or professional projects, it will increase your level of safety as you do not have to touch a surface and you can read the data even in the dark.
This multipurpose thermometer offers you plenty of versatility. It can be used alongside a standard meat thermometer in the kitchen or on the barbecue grill to record the temperature of a large piece of meat.
You can use the thermometer to safely monitor high-temperature substances like metals or plastics. Scan an air conditioning system or an appliance. Check thermal temperatures in the ceiling that may indicate potential water damage or electrical problems.

Types of Infrared Thermometers
There are two types of IR thermometers: an infrared scanning thermometer and a spot infrared thermometer.
– Scanning Infrared Thermometer
Infrared scanning thermometers like the Kizen Infrared Thermometer are ideal for scanning a wide area or a large object. Although they can be used for hot and cold temperatures and provide very good accuracy, you may have to hold the sensor closer to a surface or object to get the best reading.
– Spot Infrared Thermometer
A spot infrared thermometer like the Black+Decker Thermal Detector offers you a high level of temperature detecting accuracy. It is an excellent tool for home use and especially building, plumbing or automotive industries.
This type of infrared thermometer has a single or dual laser system that projects bright points of light or a green, red or blue spot on a surface depending on the hot or cold temperatures that it is detecting.
Thermal Camera
A thermal camera is a great investment for a professional tradesperson. As well as using cutting edge IR technology and powerful sensors, a thermal camera gives you a visual image of the temperature as well as the digital data. The only real downside to these types of IR thermometers is that they can be quite expensive.
Accuracy
The accuracy of an IR thermometer is extremely important but you need to be aware that these devices may not provide a 100% accurate reading. All IR thermometers have a slight margin of error, but the better the quality of the infrared and laser technology, the higher the level of accuracy the thermometer will deliver.
Professional-style models have an accuracy of ±1%, while entry-level models may have variations within ±2%. The accuracy will also depend on how far away the thermometer is from the surface area or object that you want to scan.
Always read the manufacture’s instructions as to how far away you need to hold the device to make sure you get the best reading.
Emissivity
Emissivity refers to the efficiency with which an object absorbs and emits infrared energy. As different types of surfaces absorb and emit radiation differently, infrared thermometers should factor in these changes in surface emissivity.
While most thermometers have fixed emissivity, advanced infrared thermometers have adjustable emissivity like the Etekcity Lasergrip Infrared Thermometer. Adjustable emissivity helps you to achieve accurate readings regardless of the surface.
Temperature Range
The temperature range of an infrared thermometer will depend on the overall design of the device. To get the right temperature range to suit your needs, you need to think about whether you will be using the device for general home use or professional projects.
If you need to use the IR thermometer for general household tasks like checking for temperature changes on the ceiling or monitoring food, a thermometer with a temperature range from -22° or -30° to 900° or 1000° degrees should be sufficient.
For professional tradesmen, a wider temperature range between -58° to 1000° or 1202° Fahrenheit provides a lot of versatility for different tasks.
Distance to Spot Ratio
The distance to spot ratio or optical resolution relates to the distance from the thermometer to the surface or object that needs to be scanned. Most IR thermometers have a DS ratio of 12:1, 20:1, or 24:1 which helps you to get the best accuracy possible.
