NIST ITS-90 Thermocouple Database - SRD 60

This database reproduces a subset of the tables and reference functions of NIST Monograph 175, 'Temperature Electromotive Force Reference Functions and Tables for the Letter-Designated Thermocouple Types Based on the ITS-90'. All temperatures used by this database are given on the International Temperature Scale of 1990 (ITS-90), and all emf values are given in units of the 1990 SI volt. Reference functions and tables are given for the eight letter-designated thermocouple types: noble-metal types B, R, and S; and base-metal types E, J, K, N, and T. The letter designations used in this database follow the recommendations of the Instrumentation, Systems, and Automation Society (ISA) and the American Society for Testing and Materials (ASTM). Version 2.0.
