Gehman Stiffness Tester | 223
Toyo Seiki · Heat Resistance / Low Temperature / Heat Aging
The Gehman Stiffness Tester evaluates the torsional stiffness of rubber at low temperature according to ISO 1432. The testing operation is automatic and specimens are twisted by means of torsion wires having nominal torsional constants at programmed test temperature. The angle of twist produced at this time is detected and is sent to the PC.
