Test Leads, Probes, and Cords

Fluke Probe Tips

Adapt Fluke test leads to perform electrical tests in tight spaces.

Fluke Test Lead Kits

These kits include a set of red and black Fluke test leads with a variety of interchangeable tips.

Fluke Test Lead Sets

Connect to Fluke multimeters with a set of red and black test leads.

Fluke Test Sensors

Take temperature readings with a Fluke multimeter.

Build-Your-Own Test Leads

Choose your own combination of test lead tips and cords.

Test Lead Sets

Pairs of red and black test leads are ready to connect to a multimeter or other electrical test equipment.

Test Lead Kits

Perform electrical tests with a set of red and black test leads and interchangeable tips.

Test Leads with Reel

Extend the distance between your multimeter and the equipment you’re testing.

Current-Sensing Test Leads

Measure current without interrupting the circuit by connecting these test leads to a multimeter or current meter.

Test Leads

Replace a test lead or complete a set with a red or black lead.

Patch Cords

Hook up electrical testing equipment and create test circuits.

BNC Test Cords

Connect oscilloscopes and other bench-top testers.

Test Lead Adapters

Convert a test lead tip style to take a new electrical measurement without switching test leads.

Alligator Clips

Spring-loaded clips create a secure temporary electrical connection for hands-free testing.

Pipe Clips

Also known as a geophone clip, this clip has rounded jaws that clamp onto battery terminal lugs and other curved surfaces for hands-free testing.

High-Current Test Clips

Test equipment that draws more than 10 amps of current. These clips are spring loaded to hold tight for hands-free testing.

Test Lead Wire

Spring Test Probes

Create an automated system to test continuity in circuit boards. Combine these spring-loaded test probes with Spring Test Probe Sockets that are permanently attached to testing fixtures.

Spring Test Probe Sockets

Mount these sockets to fixtures, attach wire from your electrical testing equipment, and add Spring Test Probes to create automated systems to test continuity in circuit boards.

Test Lead Holders

Electrical Testers

Line Splitters for Clamp-On Multimeters

Determine how much current a device with a two- or three-wire power cord uses without pulling apart the wires. The splitter isolates hot and neutral wires so you can measure AC current in either wire with a clamp-on multimeter.

Electrical Resistance Testers for Static Control

Check that your material and work surfaces won’t discharge static electricity, which can damage sensitive electronics.

Through-Panel-Mount Connectors

Before making a permanent connection, use these connectors to test a circuit. Also known as binding posts, they mount through panels to create a connection point.
