This tester is used to determine the relative stiffness characteristics of vulcanized or thermoplastic rubber. The tester will record the torsion angle of the test specimen 10 seconds after being twisted 180 degrees.

This procedure is done from 23 •c to the lowest test temperature of the test, so that the temperature (T2, T5, T10, and T100) of which the modulus values are at 2, 5, 10, and 100 can be obtained from the Temp -Angle curve diagram.
