QC-551 Long extensometer is suitable for higher than 20% elongation of rubber, plastic, PE, fabric, webbing of material which are high elongation measurement accessories. The specimen usually made dumbbell-shape. The extensometer can link with Cometech machine and auto-detect the deformation of the test piece during the test.

QC-557 Short extensometer can measure metal, hard plastic of less than 100% elongation of material deformation. During test, it can measure complete test deform rate and do not need to dismantle it when during the test. When the specimen gauge length is longer or elongation rate is bigger, customized longer extensometer is also available.

Can print out results under stand-alone operation mode.
