Device for evaluating the flexibility of rubber materials at low temperatures based on JIS K 6261-3 "Low Temperature Torsion Test" (Geman Torsion Tester, Cold Resistance Tester)
● The installation work of the test specimen can be performed efficiently. ● By using a pulse motor for the twisting operation, excitation locking is possible, making wire attachment easy. ● There is a lateral movement function for the test section, making maintenance of the cooling tank easy. ● Easy operation with a liquid crystal touch panel. ● After the test is completed, measurement data can be output to an Excel worksheet. (PC and Excel are optional) ● Reference standards: JIS K6261-3, ISO 1432
