Fluke ST120+ GFCI Socket Tester with Audible Beeper

It is very convenient to test my outlets. I have been installing some GCFI outlets, and this helped me to verify if my installation was correct. All of my testing tools are from Fluke, very trustworthy brand.

Fluke GFCI tester with a sound button. Great stuff to have.

Great little gadget.. test outlets for proper wiring, and you can trip GFCI devices on the circuit by pressing a button. I bought extras as gifts and all the recipients like this device as well.

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 is a trusted brand for testers, especially their multimeters. The Fluke GFCI test is well made and works well like other Fluke products. It's just somewhat bigger than other GFCI testers, like Sperry. Also the listing is incorrect. The GFCI tester is made in Taiwan and not China.

This Fluke ST120+ is everything I needed and more. I love the simple design for testing receptacle wiring. Fluke always makes a great product, and they are not high end priced. Their durability is always top notch, and they stand behind their products. You cannot go wrong with buying Fluke. I highly recommend buying Fluke brands when you need them.

Very good product

Simple and easy to use. Tone is great for shutting off the correct breaker - easy to understand
