Fluke Vibrating Voltage Testers

Detect voltage with three types of alerts for extra safety—light, sound, and vibration. There are LEDs that light up to show the approximate voltage level, and a digital LCD shows precise voltage measurements. Fluke testers are known for quality and durability.

Voltage Detectors

Confirm that voltage is present in receptacles, cables, and other electrical components. The detectors have light or sound alerts to indicate voltage.

Long-reach tips, tests leads with sheathed alligator clips, and test leads with needle tips must touch the electrical component you're testing to sense voltage.

Tone Generator Testers

With RJ11 Plug

With RJ45 Plug

Generate an audible signal when testing for short circuits, line continuity, or when locating a cable. Use an amplifier (sold separately) to hear the signal. These tone generators have a light signal to verify polarity.
