Explore how scientists and engineers measure the hottest temperatures with precision and reliability.
This updated edition surveys the theory and practice of pyrometry, from fundamental laws of radiation to practical instruments used in steelworks, glassmaking, porcelain production, and chemical manufacture. It blends historical insight with modern methods, showing how continuous recording and standardized standards have transformed high-temperature work.
This edition revises and enlarges the original, incorporating new optical, gas, and electrical-pyrometry approaches. It explains how instruments are calibrated, how temperature is inferred from radiation, and how these methods have shaped industrial practice around the world.
- Foundational laws of radiation and their role in temperature measurement
- Descriptions of normal and practical pyrometers, including electrical-resistance and gas-based devices
- Industrial applications in steel tempering, glass and ceramic manufacture, and chemical processes
- Discussion of standardization, calibration, and the move from workman judgment to instrument-based control
Ideal for readers of the history and practice of high-temperature measurement, and for professionals seeking a solid reference on pyrometry and its industrial impact.
