Metal Wire Torsion Testing Machine

Model: WTT Series
Description
WTT series metal wire torsion tester is mainly used in a metal factory to test the plasticity of metal wires and ropes under torsion condition. Surface flaws of steel wires may be shown during the testing process. The revolution is displayed on a 4-digit LED, with the max. revolution value displayed as 999.9. The revolution value is automatically held at the break of specimens. With computer & software, the Metal Wire Torsion tester can realize automatic control. The Metal Wire Torsion tester conforms to standard ASTM A938, ISO7800. The Metal Wire Torsion tester is an ideal QC tool for Quality Inspection & Control Department related to steel wire application.
