Fluke ST120 & ST120+ GFCI Socket Testers

The Fluke ST120 and ST120 Plus GFCI Socket Testers check that each wire in an outlet is properly connected to the building's electrical system.

These ST120 testers identify six different wiring conditions.  They feature bright LEDs and a chart on the front for quick and easy verification of the wiring of an outlet.

The ST120 Plus includes an integrated beeper that will beep anytime voltage is detected. The ST120 Plus can also provide an audible alert to the user of a hazardous voltage at the outlet, even if the wiring is incorrect.

The Fluke ST120 and ST120 Plus include a GFCI test button for GFCI outlet testing. They can verify GFCI-equipped output operation with a single button push.
