ST120+ GFCI Socket Tester with Audible Beeper

As an electrician who often works alone, the Fluke ST120+ GFCI Socket Tester with Audible Beeper has become an essential tool in my bag. The audible beeper is a game-changer—especially when I'm troubleshooting or trying to shut off a circuit and the panel is out of sight but within earshot. Being able to hear the tester respond saves me time and steps, and the sound can be turned off when not needed. It’s built with the quality you expect from Fluke, and while it’s a little pricier than some other GFCI testers, the reliability and added features are more than worth the cost. I’ll continue to repurchase this tester and highly recommend it to anyone in the trade.

Fluke, the name brand tells everything! All my work volt meters are Fluke so I have no hesitation to get this GFCI tester. This model has three big LEDs plus a sound. It is very easy to check the ground fault either by seeing the LED or by hearing the sound. Great product!

Works well!

I will confess I'm a Fluke Product fan from my days of working in tech. So when this popped up on Prime Day at a great price and decided to get it. I have another GFCI/Wiring Tester but smaller and harder to see lights showing wiring faults. But the Big Plus IMHO is the Beeper. For anyone tying to make sure you are turning off the right Circuit Breaker by yourself and running back and forth it gets old fast. And yes, I would do the old Radio plugged in and turned up works too. But now all in one great package. And yes, you can turn the Beeper OFF if you don't need it.

300 VOLT RATED...This is what you need when you test 120 volt receptacles!!! Why you ask? Maybe because hungover DJ Jazzy Trevor wired your house that day and either by accident or on purpose hooked two breakers to the hot and neutral of your branch circuit wiring and VIOLA, you have 240 volt across the hot and neutral blades. I dont know what this device would do in that case but its rated for it. MANY IF NOT ALL OTHER RECEPTACLE TESTING DEVICES SOLD ARE ONLY RATED 135 VOLTS AT BEST. I had one of those lesser devices BLOW UP IN MY HAND while testing receptacles in an office building fit up. Not saying this one wouldnt do the same thing in some bizarre circumstance but it should not in the presence of 240Volts. One star deduction, this device needs a voltage readout like the ten dollar no brand name units but they have the same problem mentioned above, not 300 volt rated AND THEY ARE NOT UL OR ETL RATED. This device is ETL rated.

Great tool. Love the audible sound. Helps troubleshooting and identifying circuits

Works perfect. Better to have one at home. Haven't tried in 220V though it's rated at 110V

Good product! Worth the extra few dollars with the tone switch.

works well
