Instrument used for measuring very high temperature is

A. Pyroscope
B. Pyrometer
C. Seismograph
D. Xylometer

Check Answer

The correct answer is: B) Pyrometer.

A pyrometer is an instrument that is used for measuring very high temperatures. It is a type of thermometer that uses an optical or electrical sensing element to measure the temperature of an object by detecting the energy emitted from its surface. Pyrometers are commonly used in industrial and scientific applications, such as in the steel and glass industries, and in laboratories.

There are several types of pyrometers, including contact pyrometers, which use a probe to physically touch the surface of the object being measured, and non-contact pyrometers, which use sensors to detect the energy emitted from the object without making physical contact. Non-contact pyrometers are often preferred for measuring high temperatures, as they do not introduce any additional heat to the system, and are less prone to damage or wear.

Gyroscopes, seismographs, and xylometers are not instruments that are used for measuring temperature. A gyroscope is a device that uses the principles of angular momentum to maintain a stable orientation, while a seismograph is an instrument that measures and records earthquakes and other ground movements. A xylometer is an instrument that is used to measure the moisture content of wood or other materials.
