Question 545General Subjects - Assistant Engineer

The correct answer is D) Extremely high temperature applications such as boiler or engine exhaust temperatures. A pyrometer is a temperature measuring device that is specifically designed for extremely high temperature applications, such as measuring the temperatures in boilers, furnaces, or engine exhaust systems. Pyrometers can typically measure temperatures from several hundred to over 3,000 degrees Fahrenheit, making them suitable for these types of high-heat environments. The other answer choices are incorrect because they do not accurately describe the primary applications of a pyrometer. Moderate to high temperatures (A), extremely low temperatures (B), and low to moderate temperatures (C) are not the typical use cases for a pyrometer, which is specifically designed for extremely high temperature measurements.
