Fluke has launched the TL 175 Twistguard test leads, which have a manually adjustable test tip guard for use in changing measurement situations.

By simply twisting the test lead, the user can change the exposed probe tip length from 3/4in (19mm) to 4/25in (4mm).

Fully extended, the TL175 Test Leads are safety rated for CAT II 1,000V use, while when retracted they are safety rated for CAT III 1,000V and CAT IV 600V.

The TL175 test leads are also Fluke’s first leads with Wearguard insulation, for which each test lead is covered by two layers of silicone insulation: red or black on the outside, and white on the inside.

If the 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 company claims.

The dual-layer silicone insulation resists melting if it comes in contact with hot surfaces.

The extra-heavy-duty strain relief, built into both the probe-end and the plug-end, has been testing beyond 30,000 bends without failure.

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

The TL175 Test Leads also offer screw threads at the base of the probe, which allows the user to add several screw-on clips, probes and speciality tips.

The threads improve measurement reliability, while the range of probe tips enhances measurement productivity.

Fluke Calibration

Fluke Corporation was founded in 1948, specialising in electrical test and measurement products. Early in its history, Fluke recognised that the very best electrical metrology would be needed to support its products and undertook to develop this capability. From this activity, the calibration business was born. Over the years, many breakthrough calibration products were introduced, establishing Fluke as a leader in electrical metrology.

In 2000, Fluke acquired Wavetek Precision Measurement. In 2001, Fluke’s calibration business expanded into the temperature field with the acquisition of Hart Scientific and then into pressure and gas flow with the acquisition of DH Instruments (2007), followed by Ruska and Pressurements (2010).

The unified business’s unmatched breadth and depth in metrology puts Fluke Calibration in a unique position to deliver today’s and tomorrow’s calibrations solutions to customers who demand the very best, supported by an organisation they can count on for the long term.
