Optical pyrometry made practical: measure high temperatures from a distance with reliable instruments you can use in shop and lab.
This edition introduces optical pyrometry as a tool for industrial and scientific work. It explains how the laws of radiation connect temperature to light, and it discusses several simple, trustworthy instruments suited to demanding environments.
- How optical pyrometers work, including the role of color, red light, and brightness in measurements.
- Practical guidance on instrument setup, calibration, and identifying sources of error.
- Comparisons of different instrument types and their suitability for various temperature ranges.
- Real-world considerations such as focusing, flame brightness, and maintaining consistent light sources.
Ideal for readers involved in metalworking, materials testing, and industrial process control who need reliable, shop-ready guidance on temperature measurement by light.
