Voltage Tester FAQs

Rated 5 out of 5 by DavidTex from A necessity for any toolbox This is a great tool to have on hand, not only for testing voltage or current, but also for testing that your GFCI outlets are functioning properly. It comes with an instruction booklet with all of the directions you need to use it safely and effectively. The unit itself has all of the features you need with a device like this, with a display panel that is very user friendly.. It is a great inexpensive tool that can work just as well for a homeowner as it does for a tradesman. It is the kind of tool that everyone needs to have on hand so they can work safely.

Rated 4 out of 5 by Anonymous from Good voltage detector Got this to help when doing low voltage tester. I like that the top of this has a slot for a magnetic strap or a strap to hold up the tester these have good covers. This is a bit larger than the klein version. This one has more clarity though when reading as far as breakdown.
