Long extensometer is suitable for elongation higher than 20% of elongation of rubber, plastic, PE, fabric, webbing of material which are high elongation measurement accessories. The specimen is usually made into dumbbell-shape. The extensometer can link with Cometech machine and auto-detect the deformation of the test piece during the test.
