A non-contact voltage tester is the quickest and simplest way to safely check for electrical current in a wire, outlet, switch, or old lamp that has mysteriously stopped working. It’s a useful tool that every electrician carries. And after talking to a 20-year veteran electrician and performing eight months of testing with seven leading models, we found that the Klein NCVT-3 is the best one to get.

The Klein detects standard and low voltage and is equipped with a handy flashlight—a nice touch for a tool you may need when the lights go out.
We recommend
Milwaukee 2203-20 10-1000V Dual Range Voltage Detector, runner-up

Milwaukee 2203-20 10-1000V Dual Range Voltage Detector

This dual-voltage tester is similar to our pick in the most important ways, but some of its minor details are a bit more annoying.
