TENSILE TEST SYSTEMS
For Wire Terminations and Similar Applications

 

THE DEPENDABLE ALPHA-TEST™ SYSTEM

MPT-250B-SC

 

 

Now available from DMC is a line of Electronic Tensile Test Systems which may be used in conjunction with SPC Programs or other Quality Control disciplines in both OEM and maintenance applications. The electronic digital readout displays are a fast and reliable source of test data.

The rugged construction and the portable design of these test machines make any of them a superior choice for on-site or laboratory use in an infinite variety of applications. The operation of the equipment is simple yet versatile, and DMC will customize the gripping jaws or other components to make test sample installation and removal an easy task.

Models are available with output display readings in Pounds, Newtons, and/or Kilograms to conform with the requirements of the user’s system. Units are available for either 115 or 230 volt power input.

It’s only natural that the company which supplies the best wire termination tools and equipment would add the very best Digital Tensile Testers to further meet the demand for fewer sources and improved support through a wider range of user needs.

The MPT-250B Motorized Wire Crimp Pull Tester is ideal when a constant  rate of pull is desired. It tests crimp strength on terminations up to size 8  in Mil-Spec applications, and size 1/0 AWG in commercial and automotive applications.

The HPT-200 Hand-Held Pull Tester blends the accuracy and rugged  design of the Alphatron pull testers 
into a self-contained, portable, rechargeable battery powered unit.  It is ideal for testing crimp strength  up to size 10 AWG in Mil-Spec applications, and size 10 AWG in commercial and automotive applications.

The PT-150H Manual Wire Crimp Pull Tester is ideal for testing crimp strength up to size 10 for Mil-Spec applications, and size 4 AWG for commercial and automotive applications.

The PT-40XP Manual Wire Crimp Pull Tester was specially designed to test the lower range tensile values of the medical and telecommunications industries, from 1 to 40 lbs.
