Pyrometry refers to the measurement of temperature_________________?
Correct answer: D. Which is of higher magnitude
- A. With the mercurial thermometer upto 350°C
- B. Directly
- C. All A., B. & C.
- D. Which is of higher magnitude
Explanation
Pyrometry is the measurement of high temperatures, generally by detecting thermal radiation without placing a sensor in direct contact with the hot object. Thus it is associated with temperatures of high magnitude.
