COMPANY PRODUCT

Application:
HEZ Series Metal Wire Torsion Tester is mainly used to test the plasticity of metal wires and ropes under
torsion condition. Surface flaws of steel wires may be shown during the testing process. It is most suitable for
quality inspection of departments related to steel wire. The revolution is displayed on a 4-digit LED. Max.
displayed revolution is 999.9. The revolution value is automatically held at the break of specimens. It
conforms to standards of ASTM A938, ISO7800.
