With a huge array of applications, the digital infrared thermometers are versatile, and will only cost anywhere between $20 to $120 depending on the brand and quality. Some uses for infrared thermometers include cooking, restaurant/kitchen management, electrical system maintenance, and monitoring cooling systems. Its main advantage is that you can take surface temperatures from afar, either for convenience or if an object is impractical or dangerous to measure otherwise.
Of course, accuracy will be the most important factor in a good infrared thermometer. Other factors to consider is its ergonomics, detection range (determined by distance: spot ratio), measurement range, response speed, and viewing port. Some very expensive, high-end models will include thermal imaging capabilities and have a built-in screen to view it on. This can be especially important in some technical fields where knowing exact temperature gradients for hot spots is key, but is not necessary for the majority of cases.

10. Etekcity Lasergrip 774 Digital Laser Infrared Thermometer Gun
The Lasergrip 774 by Etekcity is a popular, inexpensive choice for a digital thermometer. The readout screen is backlit with a bright blue to make it easy to read, and the design is lightweight. The temperature reading accuracy has a margin of 2 degrees Celsius and can read a range between -50 to 380 degrees Celsius. It has a quick response time of just a half of second, a distance to spot ratio of 12:1, and is powered by a single 9V DC battery which comes included.
9. Etekcity Lasergrip Laser Infrared Thermometer for Meat Refrigerator Pool Oven
Coming from the same family of IR thermometers, the Etekcity Lasergrip 800 has similar features as the previous model. This particular model is similar to the Lasergrip 774, except it has a much great temperature range. This thermometer can measure between -50 to 750 degrees Celsius, which is almost twice as much as the previous version. A digital thermometer is accurate within a margin of 2 degrees Celsius and has a distance spot ratio of 12:1. It is powered via a single 9V battery and has a quick response time of 500ms.
8. Kintrex IRT0421 Non-Contact Infrared Thermometers
The Kintrex IRT0421 is an excellent choice for a lightweight, convenient infrared thermometer. It is comfortable to use and provides results within one-tenth of a second. It has a measurement range of -60 to 500 degrees Celsius, and a standard distance to spot ratio of 12:1. To save power, it will convenient shut off after 15 seconds when idle. Due to its low-voltage requirements, it only requires 2 AAA batteries instead of the standard 9V battery. This increases its battery life by up to 60%. For storage and transportation, it comes with a nylon holster.
7. ennoLogic Temperature Dual Laser Non-Contact Infrared Thermometer
This temperature gun by EnnoLogic uses dual lasers for improved accuracy. It can measure from -50 to 650 degrees Celsius with an accuracy of 2C. The scan feature has a min, max, and average display setting. To make things easier to read, the display comes with a bright backlight and neutral colours. It has a distance to spot ratio of 10:1. Unlike many other models, this model has an adjustable emissivity setting which improves accuracy for different surface materials.
6. Etekcity Lasergrip Dual Laser Digital Infrared Thermometer Gun
The Lasergrip 630 by Etekcity is an improved version of the 774 and 800. It has a distance to spot ratio of 16:1 rather than 12:1 and it comes equipped with double lasers for improved measuring precision. This higher ratio allows it to measure the temperature of a smaller area at the same distance, which decreases ambient temperatures, which therefore improves the accuracy. Along with that, it has an adjustable emissivity setting between 0.1 to 1.0 to better match the material it is measuring. The temperature range goes from -50 to 580 degrees Celsius.
5. Danibos Non-Contact IR Infrared Thermometer Gun
If you’re looking for a cheap and accurate tool for cooking, this IR thermometer by Danibos is great. It has a temperature range of -50 to 380ºC, with an accuracy of 1.5%. This simple thermometer comes with an ergonomic shell with a nice, readable display. There is a button to turn on the backlighting on the display for easier reading. You can configure the display to use either Celsius or Fahrenheit. It has a 12:1 distance to spot ratio, fixed emissivity rating of 0.95, and runs on a single 9-volt battery.
4. FLIR TG165 Spot Thermal Camera
The FLIR TG165 is an imaging IR thermometer that is suitable for industrial work or other sorts of engineering maintenance. It features FLIR’s innovative Lepton IR Imaging Engine, which displays the full range of temperature on a display screen. It is easy to operate without requiring any special training. You can save images and data for later analysis, either via USB connection or a removable micro SD card. Although it is much more expensive than other IR thermometers, it can be important to derive more sound conclusions through imaging analysis.
3. Fluke FLK-VT04 Visual Infrared Thermometer
The Fluke FLK-VT04 is another imaging IR thermometer with high-tech capabilities. The imaging technology displays a visual image and an infrared heat map. This one gives you a much more precise look into potential issues compared to traditional IR thermometers, which would take multiple readings. You can adjust the blending percent between visual and infrared to get a clearer picture. The thermometer has an intuitive interface so you can use it straight out of the box without any issues. The SmartView reporting software allows you to create customizable reports out of the findings from the thermometer. This specific model comes with a rechargeable lithium-ion battery.
2. Fluke 62 MAX IR Thermometer Non-Contact
The Fluke 62 provides accurate temperature readings and comes in a durable, portable body. This one measures temperatures between -30 and 500 degrees Celsius within a margin of accuracy of 1.5 degrees Celsius. It is light enough to clip to your tool belt without making a hassle. Well-design thermometer uses precise laser technology for more accurate and repeatable measurements and has a standard 12:1 distance to spot ratio.
