Run current-carrying wires through these rings to monitor AC current flow.

Ring with a red light illuminates to indicate power.

Rings with wire leads can monitor current from up to 200 ft. away when you attach a remote LED (not included) that illuminates when current is present.

Check for the presence of AC current and voltage without making direct contact with a wire. The detector has light and sound alerts that indicate current when it is held near the electrical component.

Check insulation quality in electrical equipment such as motors and power tools. You can also take other electrical measurements with these Fluke multimeters, known for quality and durability.

These true RMS multimeters take 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 6,000-count multimeters show numbers up to 5,999.

Multimeters with calibration certificate include a NIST-traceable document stating that they have passed a test for accuracy.
