NPL can supply sources to enable radiation thermometer calibration to be performed at a range of temperatures, whilst maintaining ITS-90 traceability.
All objects at temperatures above absolute zero emit thermal radiation.
NPL can supply a range of fully certified, primary and secondary fixed-point blackbody sources for realising the ITS-90.
NPL has developed a range of capabilities to support the implementation of phosphor thermometry to solve an array of temperature measurement challenges where more traditional techniques are not suitable.
NPL can supply, with proven stability and reproducibility, high temperature fixed points (HTFPs) which are based on the melting temperature of a metal-carbon alloy.
NPL is developing new, reliable techniques using direct temperature measurement, optical fibres and thermal imaging.
NPL assessed the suitability of phosphor thermometry for reducing uncertainty in temperature measurement in nuclear material storage
We are improving techniques for reliable temperature measurement in harsh environments, including using thermographic phosphors and fibre-optics
Customer blackbody sources may be evaluated by comparison with an NPL standard source using either an infrared radiometer or a suite of transfer standard radiation thermometers operating at wavelengths from 0.65 µm to 14 μm.
