Photoelectric pyrometers are suitable in the temperature range of ________________ °C?
Correct answer: A. 800-1600
- A. 800-1600
- B. 400-1600
- C. 800-2500
- D. 400-1000
Explanation
Photoelectric pyrometers are non-contact instruments commonly used for high-temperature measurement, with a typical range of about 800 to 1600°C. Their operation depends on detecting the intensity of thermal radiation.
