High temperature of around 2000°C of incandescent gas mantles is measured by a/an __________________?
Correct answer: C. Radiation pyrometer
- A. Specially designed thermocouple
- B. Optical pyrometer
- C. Radiation pyrometer
- D. None of these
Explanation
A radiation pyrometer determines high temperature from the thermal radiation emitted by the hot body, making it suitable for temperatures near 2000°C. Unlike a contact instrument, it can measure incandescent gas mantles without touching them.
