Isotech Journal Of Thermometry by Issue

The Isotech Journal of Thermometry is a collection of technical articles dedicated specifically to thermometry. It includes articles related to temperature scales, different methods to realize them and practicle techniques used to calibrate interpolation devices such as SPRTs, IPRTs, Thermocouples, Thermistors and Pyrometers.

The Journal represents more than 20 years of published papers by Isotech and our colleagues within the Temperature Metrology industry. Most papers arose out of our own needs for improvement in our laboratories and manufacture of temperature calibration standards. Today Isotech operates a UKAS accredited primary laboratory with the lowest uncertainties of ANY private company in the world, and in fact over the full ITS-90 range, better than all National laboratories outside of NIST in America. Much of what we have accomplished is a contained within these journals, we hope you will find them both informative and technically useful.
