Fluke TL175 TwistGuard test leads

Fluke has launched TL175 TwistGuard test leads with a manually adjustable test tip guard for use in changing measurement situations.

The user can change the exposed probe tip length from 4/25 inch (4 mm) to ¾ inch (19 mm) by twisting the test lead. When the tip guard is fully extended, the TL175 test leads are safety rated for CAT III 1000 V and CAT IV 600 V use. When the tip guard is retracted, the test leads are safety rated for CAT II 1000 V use.

Each test lead is covered by two layers of silicone insulation, red or black on the outside and white on the inside. If the TL175 test leads become nicked or scuffed and white insulation is visible, the user has a visual warning that the test leads should be replaced.

The dual-layer silicone insulation resists melting if it comes in contact with hot surfaces and remains flexible in cold situations. The extra-heavy-duty strain relief, built into both the probe end and the plug end, has been tested beyond 30,000 bends without failure.
