TENSILE TEST SYSTEMS
For Wire Terminations and Similar Applications

THE DEPENDABLE ALPHA-TEST™ SYSTEM

Now available from DMC is a line of Electronics 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, and in some models the data may be output to a printer or other RS232 compatible device.

 

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 reading Pounds, Newtons and/or Kilograms to conform with the requirements of the users 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 Tester to further meet the demand for fewer sources and improved support through a wider range of user needs.

Also consult DMC for Model HPT200 hand-held pull tester which blends the accuracy and rugged design of the Alphatron pull tester into a portable battery powered unit.
