Robert, I worked on one of these with another guy on the PIC list (Gerhard Fiedler) several years ago. His unit was for the steel industry. It seems to me that it measured the temperature of what it was focused on (IR wavelength).

Has anyone tried doing an accuracy test for something like a Kanthal furnace? What's the max temp on this? I have a need to read a target that is inside a (glass)clear envelope ( also hot) will it read the envelope or the target? tia-rf ----- Original Message ----- From: M.
