– Equipped with a digital display for direct reading of results in grams or millinewtons.
Core Components:
– Pendulum Arm: Applies tearing force.
– Clamps: Secure the sample before and after the tear.
– Cutting Blade: Creates a precise slit at the start of the test.
– Digital Display Unit: Shows the tearing force result clearly and instantly.
– Counterweights: Optional weights for increasing test range (for stronger materials).
Applications of Digital Elmendorf Tearing Tester:
– Testing tear resistance of:
– Textile fabrics (especially woven)
– Paper and cardboard
– Plastic films
– Nonwovens
– Packaging materials

- Data Output Options- Some models offer USB or printer connectivity for result documentation.
How to Use a Digital Elmendorf Tearing Tester:
- Prepare the Sample – Cut the material (fabric, paper, film, etc.) to standard size (typically 100 × 63 mm for textiles) and slit it with the pre-cutter as required.
- Select Pendulum Weight – Choose the appropriate pendulum or add counterweights based on expected tear strength.
- Calibrate the Machine – Set the pendulum to its starting position and zero the display.
- Clamp the Sample – Fix one half of the sample in the stationary clamp and the other in the moving clamp.
- Cut the Initial Slit – Use the integrated blade to make a precise cut at the marked slit area (usually 20 mm).
- Release the Pendulum – Trigger the pendulum to swing and tear the sample through the pre-slit.
- Read the Result – The digital display will show the tearing force automatically (in g, mN, or cN).
- Record or Export Data – Save or print the result if your model supports USB or printer connection.
- Reset for Next Test – Reposition the pendulum and prepare a new sample for the next cycle.
Safety Tip: – Always ensure your hands are clear before releasing the pendulum.
