Operation

The operation of the ProTear is easy —simply secure the sample in the
clamps, make an initial tear and press test to release the pendulum.
The tearing resistance of the material is measured via the transference
of the potential energy stored in the raised pendulum to kinetic energy.
A portion of this energy is absorbed during the tearing of the sample
and is used as a measure of the resistance of the material to a continuing
tear. The energy required to tear the sample is reported as a percentage
of the pendulum capacity or force.

The Electronic ProTear calculates all test results and statistics
automatically and displays them immediately. Data can be exported
to a PC, directly printed or analyzed in more depth using MAP4 materials
testing software.

Precision and accuracy are increased by capturing dynamic tear data in
real-time digitally. The capacity can be changed quickly with easy-mount
technology for pendulum installation that does not require tools.
Testing capacity ranges from 200g up to 12,800g allowing for a variety
of applications with one machine.

The touch-screen display allows for quick clamping and testing.
Lab technicians can easily customize units of measurement and
reporting styles in the menu. Other functions include data entry of
sample information such as sample ID, thickness, basis weight,
sample direction and number of plies being torn.

MAP4 Software

MAP4 software is available for customers that would like to run
detailed reports and have access to in-depth data. A preloaded test
will be available and is configured to meet the industry standards
from ASTM, TAPPI, and others. The program includes a SQL Lite
database. MAP4 will provide a real-time data curve at the same
time as the results are being displayed.
