Question

jobs. allen key sets are used for conductor installations. sockets and ratchets become essential for tightening and loosening specific nuts and bolts. an infrared thermometer is used to assess the temperature of electrical components without direct contact. metering devices are the most crucial tool for electricians, enabling the identification of essential electrical properties.

a non - contact inductive tester aids in pinpointing wires that are hot, enhancing safety during tasks. a plug tester is used to determine the polarity of electrical devices. marking devices like sharpies or pencils are also necessary for accurate measurements, and a flashlight serves as a vital light source in various work environments as well.

in the electrical field, which specialty tool is used to assess the temperature of electrical components without direct contact?

• a metering device
• a plug tester
• a non - contact inductive tester
• an infrared thermometer

Explanation:

The left text explicitly states that an infrared thermometer is used to measure the temperature of electrical components without direct contact, which matches the question's requirement. Other tools have different functions: metering devices identify electrical properties, plug testers check polarity, and non-contact inductive testers find live wires.

Answer:

an infrared thermometer
