Pyrometry: A Practical Treatise on the Measurement of High Temperatures

A practical manual explains methods for measuring temperatures beyond mercury thermometers, beginning with temperature scales and calibration standards. It surveys major pyrometric techniques — thermo-electric, resistance, radiation, and optical — describing their physical principles, common instrument forms, indicators, recorders, and calibration procedures. Chapters address installation, operation, management, and special industrial and laboratory applications, with numerical examples to illustrate measurements. Emphasis is on practical guidance for obtaining reliable readings and controlling high-temperature processes, while also presenting sufficient theoretical background to understand limitations and errors.
