SLD-02 Tear Tester
Application
The SLD-02 tear tester, is specially designed to to test the tear strength of paper and cardboard. It can also be used to test the tear resistance of sheet composite materials such as textiles, leather, plastic films, metal foils, textiles, etc.
Test Process
A cutting knife in the tester is used to create a slit that ends 43mm from the far edge of the sample. Then a pendulum mechanism is released under the influence of gravity, propagating the existing slit through the remaining 43mm of the sample. During this process, the amount of energy lost by the pendulum during the tear propagation is then used to calculate the average tearing force.
Technical Features
Jaw Width: 74.8mm, holding samples of 63×76mm or 63×50mm.
Automatic Reset: The pendulum release resets automatically when manually pulled back to less than 0 degrees.
Simple Operation: Independently designed interface for ease of use.
Test Directions Indication: Horizontal, vertical, and undefined directions.
Level Adjustment: Includes left-right internal horizontal adjustment reference.
Calibration Function: For zero value (measuring loss, compensating error) with corresponding calibration weights.
Adjustable Machine Feet: Facilitates leveling, with a double-nut mechanism to prevent loosening and ensure stability during the test.
Pneumatic Sample Clamping: Prevents system errors due to human factors.
Computer-Assisted Level Adjustment: Ensures optimal testing conditions.
Multiple Pendulum Capacities: To meet different testing needs.
5-Inch Color Touch Screen: Simple and easy to use.
Air Filter/Regulator: Increases the lifespan of pneumatic components.
