Test Lead Extension Kit for Multimeters

The Fluke TL221 kit provides two silicone-insulated test leads rated for CAT III 1000V and CAT IV 600V environments. Each lead measures 4 7/8 ft and terminates in a straight shrouded plug compatible with digital multimeters, mA loop calibrators and pressure calibrators. Rubber over-moulded surfaces and finger-hugging curves give a comfortable, reliable grip during measurements.

For technicians needing extended reach on live

Electrical engineers and field service technicians who require safe voltage probing at a distance will appreciate the 10 A current rating and dual safety category approval. Users who need specialised probe tips, additional lead lengths beyond the supplied pair or non-silicone insulation should consider other accessories.

Integrates directly with standard meter inputs

The straight shrouded plugs insert into common multimeter jacks without adapters, freeing bench space by eliminating makeshift extensions. Silicone wire insulation remains flexible in cold conditions, while the one-year manufacturer warranty covers defects in materials and workmanship under normal use.

Questions about this item

What type of meter connector is required for the Fluke TL221 test lead extensions?

The kit uses straight shrouded plugs, so the multimeter or calibrator must accept that plug style for a secure connection.

Can the Fluke TL221 extensions be used with instruments rated only for CAT III 600 V?

Yes, the leads are rated CAT III 1000 V and CAT IV 600 V, so they meet or exceed the safety rating of a CAT III 600 V instrument.

How can I confirm the Fluke TL221 kit is functioning correctly after connecting it?

Verify continuity through each lead with a known good meter and check that the silicone insulation shows no damage before applying voltage.
