Final answer:
An Infrared thermometer is used for measuring surface temperatures by detecting infrared radiation, allowing for contactless and accurate temperature readings.
Step-by-step explanation:
The thermometer used to measure surface temperatures is an Infrared thermometer. Firefighters like Fireman Jason Ormand use an infrared thermometer or pyrometer to check the temperatures of different surfaces, such as an aircraft carrier's ventilation system. Infrared thermometers are preferable for such tasks as they can detect the infrared radiation emitted by objects, whose intensity correlates with the object's surface temperature. This allows for a quick and accurate temperature readout without needing physical contact with the surface being measured. This feature is particularly useful in situations where surfaces are hard to reach or too hot to touch.
The correct thermometer used to measure surface temperatures is the infrared thermometer. This type of thermometer uses infrared radiation to measure the temperature of an object without making direct contact with it. It works by detecting the radiation emitted by the object and then converting it into a temperature reading. Infrared thermometers are commonly used in various industries, such as food service, automotive, and medical, as well as for measuring body temperature.
