Weston Tew is an expert in the areas of thermal and electrical metrology, working in the three core areas of Temperature Metrology: Primary Thermometry, Interpolating Artifacts , and Thermometric Fixed Points. He has experience in precision electrical measurements, low temperature thermometry, noise thermometry, non-metal fixed points, industrial thermometry, and special applications in temperature measurement. He is an author of more than 80 publications on these subjects.
Dr. Tew is a member the International Electrotechnical Commission, Working Group 5 on Temperature Sensors of the subcommittee 65B, the ASTM International Committee E20 on Temperature Measurement; The ANSI US Technical Advisory Group for the IEC, and the American Physical Society. He is a fellow of the ASTM and is the current chair of the E20.07 subcommittee on Fundamentals (of Temperature Measurement).
He has been a staff physicist in the NIST Process Measurements Division and the Sensor Science Division since 1993 where he is responsible for realization and maintenance of the ITS-90 below 84 K. His research interests are in special applications for temperature measurement, temperature standards, platinum resistance thermometry, dilute magnetic alloy thermometry, Johnson noise thermometry, fixed points, and phase equilibria.
