Abstract
A surface temperature measuring apparatus is arranged to comprise means for conducting a first radiant energy generated from an object to be measured, said energy conducting means being provided opposite to said object, and reference radiation source means provided to mask the influence of radiation noise from the furnace on a radiometer and to generate a second radiation whose level is substantially determinable, whereby the surface temperature of said object can be determined from the detected values of said first and second radiations.
