Electronic Elmendorf ProTear
You want your test results to fall between 20% and 80% of your pendulum capacity. For example, if you are using a 1600 gram pendulum, you should expect to get tear results between 1280 grams and 320 grams.

The electronic model provides several enhancements over the mechanical model. All test results and statistics are calculated automatically and displayed on the built-in screen. An RS-232 port enables test results to be transmitted to a printer or computer.
Precision and accuracy are increased as pendulum movement is monitored by a digital encoder.
Ergonomically designed for ease of operation and conservation of laboratory space, the ProTear Electronic Model incorporates both mechanics and electronics into a single footprint design.
Other standard features of the electronic model include air-actuated pendulum release and sample clamps, microcomputer-assisted pendulum balancing and a membrane switch display panel.
The control panel provides one-touch clamping and test capabilities. Other functions include data entry of sample information such as sample ID, thickness, basis weight, sample direction and number of plies being torn. The “Units” key enables the simple configuration of result units.

Operation
The operation of the ProTear is easy —simply secure the sample in the two clamps, make an initial tear with the attached blade and 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 materials resistance to a continuing tear. The energy required to tear the sample is reported as a percentage of the pendulum capacity or force.
Fast, Flexible Software
The ProTear’s standard menu-driven software provides total control over test parameters and reports test data seconds after test completion.
