ENGLISH
Emissivity is the relative ability of a surface to emit energy by radition. Each
type of surface (metal, brick, wood, etc.) has a different emissivity level
which must be accounted for when taking a measurement with an infrared
thermometer.
The IR3000 has a variable emissivity from 0.10 to 1.00 which allows
accurate measurement of most types of materials. Shiny bright surfaces
(i.e. chrome, new copper, white boards) have a much lower emissivity
than fl at black materials. The emissivity of the IR3000 should be set
manually according to the chart below in order to obtain the most accurate
measurements. The chart is for guidance only, as the emissivity of objects
varies depending on surface fi nish, measurement wavelength, fi eld of view,
temperature, and the shape of the object.
