Fluke Corporation offers the new TL 175 TwistGuard test leads, the only ones in the world with manually adjustable probe tip protection for use in varying measurement situations. By simply twisting the test lead, the user can change the exposed probe tip length from 19 mm to 4 mm. When fully extended, the TL175 test leads offer a CAT II 1000 V safety rating. When retracted, the test leads offer a CAT III 1000 V and CAT IV 600 V safety rating.
The new TL175 test leads are also Fluke's first leads with WearGuard insulation. Each test lead is coated with two layers of silicone insulation: red or black on the outside and white on the inside. If the TL175 test leads are rubbed or scraped and the white insulation is visible, the user has a visual indication that the test leads need to be replaced.
Until the WearGuard indicator shows excessive wear, TL175 test leads are designed to outlast any other lead currently available. The double-layer silicone insulation resists melting if it comes into contact with hot surfaces. The leads feature heavy-duty terminations at both the tip and connector ends, with over 30,000 bend tests without failure. The universal input connectors are compatible with all major brands of digital multimeters with 4 mm input jacks.
The TL175 test leads also feature a threaded connection at the base of the probe. This allows the user to attach various clamps, probes, and screw-on specialty tips. The threads improve measurement reliability, while the wide range of tips increases measurement productivity.
