LCD Voltage Tester for 120V Outlets

This GFCI outlet tester combines a colour LCD with bottom indicator lights to show real-time voltage and seven wiring-fault codes on North American 3-wire 120V receptacles. It is powered by an internal battery and carries a CAT II 125V rating for household electrical diagnostics.

Homeowners and inspectors checking standard outlets

The auto-hold function freezes readings so results can be seen on outlets behind furniture or in tight corners. The tool does not test 300V industrial circuits, three-phase panels or low-voltage data wiring, and it cannot verify GFCI operation on receptacles without a ground path.

Single-button GFCI trip test

Pressing and holding the built-in button for two seconds forces the breaker to trip if ground-fault protection is working, giving an immediate pass-or-fail indication for the safety device.

Questions about this item

What does the 120 V AC rating mean for everyday outlet testing?

It means the tester is designed for standard North American household receptacles and will show live voltage on the LCD when plugged into a correctly wired 120 V outlet.

How does the CAT II 300 V safety rating limit where I can use this tool?

The CAT II 300 V rating covers measurements on branch circuits like wall outlets, but it is not rated for service-entrance panels or higher-energy distribution equipment.

Will the three-prong plug fit older two-slot receptacles without an adapter?

No, the tester has a standard three-prong North American plug that requires a grounded three-slot outlet; it cannot be inserted into vintage two-slot receptacles.
