Understanding Pyrometers
Pyrometers are specialized instruments designed to measure high temperatures without needing direct contact with the object being measured. They are particularly useful in industrial settings where conventional thermometers would not withstand extreme conditions.

How Pyrometers Work
- **Principle of Operation:** Pyrometers primarily operate based on the measurement of thermal radiation emitted by an object. The emitted radiation is analyzed to determine the object's temperature.
- **Types of Pyrometers:** There are several types of pyrometers, including:
- **Optical Pyrometers:** Measure temperature by comparing the brightness of an object to a reference light source.
- **Infrared Pyrometers:** Utilize infrared radiation detection to measure temperature from a distance.

Applications of Pyrometers
- **High-Temperature Environments:** Pyrometers are essential in industries such as metallurgy, glass manufacturing, and ceramics, where temperatures can exceed the limits of standard thermometers.
- **Non-Contact Measurement:** The non-contact nature of pyrometers makes them ideal for measuring the temperature of moving objects or hazardous materials.

Conclusion
In summary, the correct answer to the question is option 'C', as pyrometers specifically measure high temperatures. Their unique design and functionality allow for accurate and efficient temperature readings in challenging conditions, making them invaluable in various industrial applications.
