Unit: mm D : S = 16 : 1
Distance (D) : Spot size (S)
To avoid interference with another object's
infrared light move closer to the object until the
D:S ratio equals 12:1.

Missivity
Emissivity describes the energy emission
characteristics of materials. Enhancing
emissivity means enlarging the emission
capabilities of an object. Organic materials
and oxidized metal surfaces have emissivity
between 0.85-0.98. The device was designed
for emissivity that equals 0.95. If the emissivity
of the object is lower than 0.95m the
measured temperature is lower than the actual
temperature and vica versa.
A shiny metal surface or a smooth painted
surface has low emissivity. Pay attention to the
effects of emissivity!
