Thanks for the informative response. The pyrometer I used many years ago was an optical pyrometer with a wire superimposed over a small viewing scope. The unit heated the wire to a specific temperature and you overlaid it on the object to be measured. When it "disappeared" you were on the correct temperature. This was for getter firing on vacuum dewars.
