Pick out the most suitable instrument for measuring temperature in the range of \(-40^\circ C\) to \(425^\circ C\)
Show Hint
For mechanical, wide-range measurement → use bimetallic thermometers.

- Bimetallic thermometer
- Radiation pyrometer
- Mercury thermometer
- Infrared thermometer
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Bimetallic thermometers cover a wide temperature range and are rugged.
Mercury thermometers have lower upper limits, pyrometers used at high temperature only.
Mercury thermometers have lower upper limits, pyrometers used at high temperature only.
