Historical/Discontinued Product

The MPT-250B has been discontinued and has been replaced with the new and improved MPT-250C.

The MPT-250B Motorized Wire Crimp Pull Tester has a range from five pounds force to two-hundred and fifty pounds (2-113 Kg, 22-1112 N).

You can expect the same precision and dependability that has established all ALPHATRON® testers as the first choice for wire harness builders and component suppliers throughout the industry. The 250 pound capacity of this tester will extend the range of testing capabilities to size 8 Mil-Spec applications*, and size 1/0 AWG in commercial and automotive applications** (Reference AS7928 and UL486 Respectively).

The portable design (25 pounds, 9.5”x10”x16”) and the rugged construction (machined aluminum and steel) contribute to the versatility and reliability of the MPT-250B Pull Tester. A variety of options, including standard and custom grips for all types of wire terminations are available on this tester. The operation of the tester is simple and has automatic reset and auto-stop features incorporated into the design. The peak-hold digital display indicates the highest pull force that is measured by the accurate load cell/digital processor until the reset switch is pressed.

* Size 8 MIL Spec wire pull test is typically 220 pounds force. Sample may not break at 250 pounds.
** May require special grips due to wire diameter.
