MONITOR/TEAR" TESTER • Digital display •Storage and editing of up to 500 readings • Easily interchangeable pendulums ranging from •Auto calibration of pendulum •Selectable units (percentage, millinewtons, grams) •Settable limits, Statistics, Average, Standard devia- tion, high/low results •Grips and pendulum releases are pneumatic •Calculates and displays average tearing force for single ply values in millinewtons or gram force • Report printout with optional printer TEAR TESTING Tear testing determines the force required to continue the tearing of an initial cut in sheet materials. This is also used to evaluate strength of perforated materials such as postal reply cards. The Monitor/Tear™ is an automated tear tester equipped with an optical encoder, measuring the angu- lar position of the pendulum during the tearing opera- tion, and converting this measurement to tear units.
