What are receptacle testers used to measure?

Explanation:
Receptacle testers verify that an electrical outlet is wired correctly and that the hot, neutral, and ground are connected as intended. They plug into the outlet and use internal indicators to show polarity and wiring integrity, revealing conditions like open ground, open neutral, or reversed hot and neutral. They’re not designed to measure the voltage on the main power line, nor to gauge ambient temperature around outlets, and they do not test insulation resistance of wires. For those measurements, you’d use a voltmeter, an insulation tester, or a thermometer, respectively.
