TEMPERATURE FIXED-POINT CELL, TEMPERATURE FIXED-POINT DEVICE AND CALIBRATION METHOD FOR TEMPERATURE GAUGE

摘要

PPROBLEM TO BE SOLVED: To provide a temperature fixed-point cell which can realize a fixed point in a temperature zone ranging from 1,100C to over 3,000C, and can prevent a crack from occurring in a crucible when used. PSOLUTION: The temperature fixed-point cell is made up of the crucible whose element is carbon, and a fixed-point material enclosed in the crucible. The fixed-point material of the temperature fixed-point cell is made of a porous body including carbon powder wherein an eutectic of carbon and a metal or metal carbide exists.
