The GESTER GT-C11A Elmendorf Tear Tester is a precision laboratory instrument engineered to measure the ballistic tear propagation resistance of woven fabrics, non-woven materials, paperboard, plastic films, and technical textiles. Utilizing classic pendulum-swing physics enhanced with modern microcomputer processing and high-precision optical encoders, the GT-C11A delivers instant, highly repeatable tear force measurements. Designed for QA/QC textile laboratories, packaging manufacturers, and research centers, the GT-C11A eliminates manual reading errors through digital force calculation and automated pneumatic specimen clamping. It fully satisfies international compliance standards including ASTM D1424, ISO 1974, ASTM D5734, JIS K7128.
