Using a reference emissivity coefficient
Apply matte black colour to a part of the surface to be measured. This part has an
emissivity of 94 %. At first, measure the temperature of the coloured part. Then
make a comparative measurement right next to the coloured part and adjust the
emissivity on the pyrometer until it displays the previous measurement reading
again.
