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.
