Fluke ST120+ GFCI Socket Tester with Beeper

Fluke ST120 plus GFCI Socket Tester with Beeper

The Fluke ST120+ GFCI Outlet Tester beeps and verifies that each wire in the outlet is properly connected to the building’s electrical system. With the bright LED light and included diagram, you can check the outlet’s wiring quickly and easily. Capable of identifying some common wiring errors including reversed wire, neutral wire and open ground wire, the ST120+ will give you confidence for your next job.

Audible alert helps you work faster, safer

The ST120+ also gives you a unique audible alert whenever voltage is detected. Save time trying to figure out which breaker is connected to which outlet. Simply plug in the outlet tester, go to the breaker panel, and listen for the beep off – or on – as you flip the breaker. Once this is done, you have found the correct breaker. Time – and travel – is saved.When enabled, the built-in beeper can also warn you of dangerous voltages at the outlet, even if the wiring is incorrect. Do you work in an office, hospital, or other places where you don’t want to disturb others? No problem – the beep can be turned off.

One-button GFCI tests

The GFCI test button found on the ST120+ outlet tester also allows you to test the operation of GFCI outlets. With just one touch, the ST120+ can test the operation of your GFCI equipped outlet. If the GFCI works as expected then great, you can continue. If not, it’s time to take a closer look.
