WebZero emissivity means that no matter what an object’s temperature, no light will be radiated. An emissivity of one means that the surface will radiate perfectly at all wavelengths. Scientists give these special perfectly radiating objects the name “blackbody.” Objects with emissivity very close to one are also usually called blackbodies.

WebIR sensors measure targets as small as .43mm (.017 in). The limitation is the temperature and emissivity. As the temperature goes lower or the emissivity is lower, then the instrument cannot go as small in spot size. The sensor will have to be placed closer to the target and a close focus lens will have to be utilized. the 3 layers of the heart wallWebInfrared (IR) thermometers enable you to measure temperature quickly, at a distance, and without touching the object you're measuring.
