Class Information
Number: 356/44
Name: Optics: measuring and testing > Optical pyrometers > With sample engaging rod or tube
Description: Subject matter wherein there is structure such as a rod or tube to contain and contact a heated solid or fluid or to be immersed into a heated fluid whereby there is a heat exchange from the heated solid or fluid, which causes the structure to emit light or the structure allows the light emitted from a heated solid or fluid to be directly transmitted to a detector which analyzes this light in terms of temperature.
