10 Determining and Setting Emissivity
In pyrometry, the specific radiation characteristics of the measured object
will influence the generated temperature data. In order to produce accu-
rate and reliable temperature readings, the pyrometer must be config-
ured according to the specific material constant (emissivity).

To determine the correct setting of the emissivity of a compara-
tive measurement is carried out by a contact measurement. In
order to minimize measurement differences between the two
different physical measuring methods, the comparison meas-
urement is almost the same time and performs at the same
measuring point as possible
