Best Infrared Thermometer Buyer’s Guide

Features to Consider

  1. 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.
  2. 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.
  3. 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.
  4. 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.
