Main Feature

1.1 YYU series axial deformation extensometer, which is applicable to metal, non-metallic material test. It includes regular extensometer, average strain extensometer, special extensometer (large standard steel hinge line, concrete, rocks, wood, etc.) Used to measure elastic modulus E, provisions non-proportional extension intensity RP, stipulated total extension strength RT, various elongations, strain hardening exponent N and other parameters.

1.2 YYJ series fracture mechanics and the lateral deformation of extension plan, is used to measure Poisson's ratio U, plastic strain R, KIC, COD parameters.

Also used in reverse shear modulus G, regulation disproportional torsion stress RP (for example Rp0.015, Rp0.3, etc.) of the torsion extensometer.

1.3 YYS series 0.5 level high-precision axial static, dynamic extensometer.
