HHFTVF Spectropyrometer Purchase

The HIVE facility uses a unique spectropyrometer, that measures surface temperature without emissivity data and includes uncertainty. We seek another for the HHFTVF facility. This equipment is to be used on a high heat flux test facility which primarily, though not exclusively, uses induction heating to heat metallic samples in a vacuum. The equipment is required to provide a non-contact temperature measurement through a window of the vacuum vessel. The key point is that for the surface of interest, the emissivity, emissivity profile with temperature/wavelength/surface finish etc. is unknown and/or spatio-temporally changing. The equipment needs to measure surface temperature without the emissivity being inputted by the user. We need this as typical non-contact temperature (thermography) measurements require accurate knowledge of the emissivity of a surface to provide an accurate temperature measurement, but we do not have this information for the surfaces of interest. A detailed list of requirements can be seen in the attached documents, which can be downloaded for viewing.
