Question

Instrument used for measuring very high temperature is:

• A. Periscope
• B. Pyrometer
• C. Seismograph
• D. Xylometer

Answer 1

Answer:

B. Pyrometer

• The instrument primarily used for measuring very high temperatures is a Pyrometer.

• Pyrometers work by measuring the thermal radiation emitted by an object, rather than by direct contact. This makes them ideal for measuring temperatures in environments that are too hot or inaccessible for traditional contact thermometers (like mercury thermometers or even many thermocouples). They can measure temperatures up to 3000°C or higher, often used in furnaces, molten metals, and other extreme industrial applications.
