New TL175 TwistGuard™ Test Leads change tip length with a single twist, earning CAT II, CAT III and CAT IV safety ratings

Sydney, April 5, 2011 – Fluke Corporation, the global leader in portable electronic test and measurement technology has announced the availability of the new TL175 TwistGuard Test Leads, the only test leads with a manually adjustable test tip guard for use in changing measurement situations.

By twisting the test lead, the user can change the exposed probe tip length from 4/25 inch (4 mm) to ¾ inch (19 mm). 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.

WearGuard™ indicator provides added safety factor
The new TL175 Test Leads are also Fluke’s first leads with WearGuard™ insulation.

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.

While the WearGuard indicator shows excessive wear, the TL175 Test Leads are designed to last longer than any other leads currently available. 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.

The universal input plugs work with all popular brands of digital multimeters with 4 mm input jacks.

Screw-on tips add versatility
The TL175 Test Leads also offer screw threads at the base of the probe. This lets the user add screw-on clips, probes and specialty tips. The threads improve measurement reliability, while the wide range of probe tips enhances measurement productivity.

Pricing and availability
Fluke’s new TL175 TwistGuard Test Leads are available for immediate purchase at leading electronic and electrical distributors worldwide.
