Emissivity
Most organic materials (ca 90 %) with a painted
or oxidised surface have an emission ratio of 0.95
(preset on the IR thermometer). Shiny materials
should be masked or painted black before
measuring. Give the tape or paint the time to reach
the temperature of the measuring object. Measure
the masked or painted surface.
