Description
The GenElm Series Elmendorf Tearing Tester is a professional laboratory instrument used to measure the tear resistance of different materials. It follows international standards, including ASTM, ISO, and DIN. The system is based on the pendulum method of testing, giving laboratories clear and precise data for both research and everyday quality control.
This equipment can be applied to many types of materials such as fabrics, plastic films, paper, nonwoven textiles, and thin foils. By testing how a tear develops in these materials, the GenElm Series helps evaluate strength, performance, and compliance with industry requirements. The results are especially valuable for production lines, product testing facilities, and research centers that need dependable measurements of material durability.
The GenElm Series comes with a simple touch-screen interface, automatic specimen cutting, and pneumatic clamping for stable handling of samples. Different pendulum options allow the user to cover several testing ranges, while the built-in system collects and processes the data. This combination of functions makes the instrument practical for everyday laboratory work and a reliable solution for routine testing.

Technical Specifications
The GenElm Series is available in two versions to cover different material testing needs. The 64 N model supports three ranges (0–16 N, 0–32 N, and 0–64 N), making it suitable for textiles, packaging films, and paper products. The 128 N high-energy model extends the capacity up to 128 N, which is required for tougher or more technical materials. Both versions rely on the same pendulum principle, ensuring a unified approach to tear strength measurement.
Despite the difference in maximum load, both models share identical design features and geometry. Each tester is built with a clamp gap of 7.0 ± 0.25 mm, a slit length of 20 ± 0.2 mm, and a tear travel of 43 ± 0.15 mm. In this context, “N” stands for newtons, representing the pendulum capacity. This structure allows laboratories to choose the configuration that matches their materials without compromising consistency across tests.
