With a simple, ergonomic design, an easy-to-read backlit LCD, and easy conversion between F and C, this is a solid choice for those looking for the best-infrared thermometer for body temperature to use at home on adults, kids, and babies. It can measure human body temperature from a distance of a few cm from the forehead and gives a readout that promises accuracy of +/- just 0.1º C, which is a smaller margin of error than most mercury thermometers. It requires 2 AAA batteries, but fortunately it ships with batteries included.
As with our other recommendations for the best-infrared thermometer for humans, this one has the key advantage of allowing a no contact first line fever assessment. While it lacks some of the features like memory and fever chart functions, that you can find on other medical infrared thermometers, it does provide handy ambient temperature and surface temp modes. A great no-contact digital infrared thermometer you can find on Amazon.com is the Sovarcate Digital Laser Temperature Gun with Color Display. It has a temperature range of (-58 to 1112°F) and an emissivity adjustable range of 0.1-1.0 (pre-set 0.95) and is intended to measure the internal temperature of meat, ice, plastics, steel, etc. If you’re looking for additional medical equipment, you might be interested in the best body fat monitor too.

How We Decided
In order to bring you the best-infrared thermometers for a variety of use cases, we focused on accuracy, durability, and reliability of measurement.
For selecting among infrared thermometers for human body temperature measurement we looked for models that had a reading time of 1.5 seconds or less and a .5º or smaller margin of error. While with home use infrared thermometers, medical diagnostic grade accuracy may not always be possible, they still provide useful first-line info and the best-infrared body thermometers are as accurate as traditional mercury thermometers.
We also took into consideration battery type and life, giving preference to infrared thermometers that use easy-to-find AAA batteries or include rechargeable Li-ion batteries. Smart device compatibility and memory functions were a bonus.
For our picks for the best-infrared thermometer in all categories, features like emissivity adjustment and dual laser sights were a bonus. If you suffer from scoliosis, or you need a good brace to support your lumbar region, find some great options in our best back brace guide.
Best Infrared Thermometer Buyer’s Guide
Features to Consider
- Temperature Range
Infrared thermometers are optimized to read certain temperature ranges, and depending on your intended use, this can be the deciding factor in which product is the best-infrared thermometer for you. If you’re looking for the best-infrared thermometer for pizza ovens, for example, you’ll want one that has accuracy up to at least 800º F. HVAC repair work, on the other hand, will require more sensitivity in the 40-120º F range. And if you’re looking for the best-infrared thermometer for human body temperature measurement, a range of just 10-12ºF, or from around 94-106º F is all you’ll need, but you’ll want much greater precision than you get with industrial infrared thermometers. - Sensitivity
Along those lines, the sensitivity you’ll need depends on what you’re using it for. The best-infrared thermometer for humans, for example, will have a precision of less than .1º margin of error. If you’re looking to measure heat build-up on your car’s tires, however, an error of +/- 2% or several tens of degrees is perfectly acceptable. - Distance to Spot Ratio
This refers to the ratio of the distance at which you can measure a surface and the area of the surface the infrared thermometer will measure. For medical infrared thermometers, a ratio close to 1:1 may suffice, as they are typically held within a few centimeters of the forehead or ear. If you’re looking for the best-infrared thermometer for pizza oven, auto repair, or water heater work, however, you’ll want a much higher ratio so you can measure surface temp from a comfortable distance. - Emissivity
Emissivity refers to the ability of an object or material to emit infrared energy, which IR thermometers use to measure the temperature of an object. Emissivity values range from 0, for a perfectly reflective surface, to 1.0 for a perfectly absorbing surface. So, a shiny mirror or piece of foil would be close to zero, while a matte black insulating box would be close to 1.0. Most everyday objects and surfaces have emissivity values near .95, and for this reason, many simpler IR thermometers have a fixed emissivity calibration at .95. If, however, you measure very differently reflective objects–think a brake disc versus a tire– you might want to look into an infrared thermometer with user-adjustable emissivity calibration.
