EmissivityConsiderations

Emissivityrepresentsthe reflectivityofamaterial.Forthismeter,theemissivitycanbe adjusted

from 0.10~1.00 (see Emissivity Adjust section above). Most organic materials and painted or

oxidizedsurfaceshaveanemissivityofapproximately0.95.Ifpossible,maskingtapeorflatblack

paintshouldbeappliedtocoverthemeasuredsurface.

Waitaperiodoftimetoallowthetapeorpainttoreachthermalequilibriumwiththesurfaceof

thecoveredobject.Measurethetemperatureofthesurfacecoveredwithtapeorpaintonly.
