A Glass Surface Temperature Pyrometer

JSGT 1954 V38 T457-T469

A pyrometer is described which has been developed for the measurement of the surface temperature of glass. The temperature range covered is 150°-550°. The theory underlying the design of the pyrometer, which is sensitive over a selected band of wavelengths in the infra-red, is outlined, and the errors which may be encountered in practice are discussed.
