Introduction of the YYU extensometer:
YYU series axial deformation extensometer is suitable for testing of metal and non-metal materials. Including conventional extensometer, average strain extensometer, special extensometer (large gauge steel strand, concrete, rock, wood, etc.)
Used to measure elastic modulus E, prescribed non-proportional elongation strength RP, prescribed total elongation strength Rt, various elongations, strain hardening index n and other parameters.
