How much temperature is measured by radiation pyrometer?
Radiation pyrometers measure temperatures above 800°C. These instruments detect thermal radiation emitted by an object and convert it into a temperature reading. They are commonly used in high-temperature industrial processes such as metalworking, ceramics, and glass manufacturing, where temperatures exceed 800°C.

The correct answer is option D. Radiation pyrometers measure temperatures above 800°C. These devices operate based on the principle of detecting thermal radiation emitted by an object and converting it into a temperature reading. They are commonly used in industries such as metal processing, glass manufacturing, and ceramics production, where temperatures often exceed 800°C. While other temperature ranges (options A, B, and C) may be measured by different types of thermometers, radiation pyrometers specifically target high-temperature applications. Therefore, option D, “Above 800 °C,” accurately represents the temperature range typically measured by radiation pyrometers, distinguishing them from thermometers designed for lower temperature ranges.
