Mark-10 WT3-201M Wire Terminal Tester, 200 lbF, 110V


The WT3-201M offers both destructive and non-destructive testing. It secures wires with a rotating turret-style fixture, with slots of various widths up to 0.25″ (6.3 mm).

Product Description

The WT3-201M Wire Terminal Tester measures the pull-off force of wire and tube terminations. It accommodates most insulation types and wires up to AWG 3 (0.25 inches [6.3 mm] OD ). Also, the tester conforms to UL, ISO, ASTM, SAE, MIL, and other requirements for destructive testing. Non-destructive testing is also possible—such as pulling to a load or maintaining a load for a specified period of time, per UL 486A/B requirements.

The WT3-201M features statistical calculation and data storage for up to 2,000 readings. It can transfer data to a PC via USB, RS-232, Mitutoyo digimatic, or analog outputs. As with all Mark-10 products, it includes a 3-year warranty.
