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. Noncontact detectors can sense voltage when brought near the electrical component.

High-Voltage Detectors

Safely check for the presence of voltage in high-voltage equipment and lines. This noncontact detector checks for voltage by sensing electrostatic fields when brought near the electrical component. Light and sound alerts indicate voltage.

For testing 1,500-122,000V AC, a hot stick is required (not included). It attaches to the high-voltage detector to extend your reach and detect voltage from a distance.

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.

Fluke Wireless Remote-Reading Voltage Meters

Measure voltage from a distance with these wireless connection-enabled meters that transmit readings to a separate display. Fluke is known for quality and durability.

The meters work with the Fluke 3000 FC multimeter, a computer with a Fluke pc3000 FC connector plugged in (not included), or a mobile device that has the Fluke Connect app.

The true RMS meter takes accurate AC measurements regardless of the load type or sine wave shape. This is important for testing electronic devices that draw current in short pulses that can distort the shape of the wave, such as computers and adjustable-speed drives.

Display count is an industry designation and not an actual value. These 1,000-count meters show numbers up to 999.
