All objects emit thermal energy. Emitted energy quantity depends on the surface temperature and object emis-
sivity. The product can measure emission on the surface of object and calculate object temperature. Objects with
different surfaces but with the same temperature can emit different quantity of thermal energy. Many objects (e.g.
coated metal, wood, water, skin and texture) possess high emissivity (0,9 and more), and emit more energy than
glossy surfaces and uncoated metal, because their emissivity is less than 0,6. Adjustment of emissivity helps to
take this feature into consideration and minimize inaccuracy of temperature measurement.
