Polymer Test announces the addition of two new features
to its popular LMI4000 Series Melt Indexers. In addition
to the previously available pneumatic weight raising and
lowering system, a new electric weight raising and lowering
system is now available. This electric system is ideal
for applications requiring the use of heavy weights, but
where shop air is not readily available.
LMI4000
also offers an "auto cut-off" feature that automates
the manual ASTM D1238 test method ‘A’. With
this feature, a solenoid driven knife automatically cuts
the extrudate as it leaves the melt indexer die at operator
programmed intervals during the test. This new automated
system removes the influence of the operator from test
method ‘A" and makes test results more repeatable.
LMI4000
features a 32-bit microprocessor that enables unparalleled
control of material test parameters as well as the ability
to perform self-diagnostics and digital calibrations.
The instrument offers simple push-button RTD calibration
and is available with an optional digital encoder for
precise measurement of piston displacement and rate of
descent. Personal computer communications capability and
the company’s MIWORKS for Windows™ software,
which acts as a melt index test database, are also available.
