Abstract
Markin M.O., Markina O.M., Poryev V.A. The influence of the equivalent wavelength to the accuracy of the bispectral television pyrometer. The problem of using the bispectral television pyrometer for the measurement of the temperature of the melting zone is analyzed. The influence of
the error in the determination of the equivalent wavelength to the error of the temperature measurement is analyzed. The practical recommendations on the increasing the accuracy of bispectral television pyrometers is presented.
