The ability of the object’s surface to emit heat.rIngeneral,infraredthermometerscaneasilymeasurenon-metallicsurfacesbecausetheyemitmostoftheirpotentialheat.Metallicsurfaces,ontheotherhand,arepooremittersandrequirespecialtreatmentbeforeinfraredthermometerscanaccuratelymeasuretheirtem-perature.Fortunately,thatspecialtreatmentissimpleandcanbeeasilyaccomplishedbymark-ingthemetallicsurfaceyouwishtomeasurewithanon-metallicsubstancesuchaspaint,grease,oiloreventransparenttape.Werecom-mendmarkingmetallicsurfaceswithasolidpaintmarker.*Tomakethingseasy,Exergenprovidesamarkerwitheachunit.
