Voltage presence is useful information to have when troubleshooting or working on a failed asset. The first tool you’ll reach for is a non-contact voltage detector, also known as a voltage tester. These pocket-sized detectors immediately identify the presence of voltage.

Certified up to CAT IV 1000 V, the Fluke non-contact voltage detectors are rugged, safe and easy to use. A built-in sensor at the tip of the tool detects the presence of voltage when touching a conductor, outlet or supply cord. By holding the detector, you are the ground reference through capacitive coupling. When the tip glows red and the unit beeps, you know voltage is present.
Compare non-contact voltage detectors
Fluke offers five tools in the non-contact voltage detector family. Testers that detect 20 to 90 volts, 90 to a thousand volts and the LVD2, which incorporates a flash light and detects up to 600 volts. Below is an easy-to-read comparison chart of all five tools.
