Why This Tool Is Worth It

Most basic outlet testers rely on a pattern of small lights that you have to decode with a chart. The RT250 replaces that guesswork with a large backlit LCD that shows the voltage reading and clearly identifies the wiring condition.

It also tests GFCI outlets and displays the trip time, which makes troubleshooting faster and more accurate. Its patent pending detection system identifies open neutral and open ground faults, two problems many basic testers can miss.

The Auto Hold feature is a smart touch too. When you're testing an outlet behind furniture, inside a cabinet, or tucked under a bench, it holds the reading so you can pull the tester out and read it clearly. For $16, it's a small investment that adds a big layer of safety to your shop and home.

Features
