Christopher W. Meyer (Fed)

Dr. Christopher Meyer has been a member of the NIST Thermodynamic Metrology Group since 1991. During this time he has been involved in projects involving temperature, humidity and pressure measurement and has developed expertise in these areas. He has authored more than 60 papers on these subjects. Meyer constructed the NIST Low Temperature Realization Facility, which realizes the ITS-90 temperature scale from 0.65 K to 85 K and serves as NIST's primary temperature standard below 25 K. He participated in the development of the NIST Hybrid Humidity Generator, which serves as NIST's primary humidity standard over the dew/frost point range -85 °C to 85 °C. Meyer has also been involved in numerous research projects in thermometry, including thermodynamic temperature measurement using acoustic thermometry, temperature measurement of silicon wafers for Rapid Thermal Processing (RTP), and microscopic temperature measurement using fluorescence techniques. He has also performed humidity research projects, studying primary humidity measurement using a gravimetric hygrometer, dew points in compressed gases, and the water-vapor permeability of firefighter fabrics.

From 2017 to 2018 Meyer worked as a NIST secondee at the BIPM (Bureau International des Poids et Mesures), helping develop a facility for making high-accuracy measurements of the amount fraction of carbon dioxide in air using a PVT (pressure, volume and temperature) method.

Meyer is currently responsible for the maintenance and realization of NIST humidity standards and pressure standards using piston gauges. He is an active member of the CCT (Consultative Committee on Thermometry) Working Groups WG-Hu on humidity measurement and WG-KC on key comparisons for temperature and humidity standards. Meyer is also an active member of ASTM Committee E20 on Temperature Measurement, where he is chair of its subcommittee on Digital Contact. He is a technical assessor for NVLAP (National Voluntary Laboratory Assessment Program).
