FIELD: instrument making.
SUBSTANCE: invention relates to test equipment. Proposed unit comprises rotation drive articulated with active gripper, passive element arranged aligned with the former on torsion of torque metre, and specimens contact heating device. It comprises additionally second active gripper and second passive gripper arranged aligned on second torsion. Both active grippers are coupled with rotation drive via opposed worm gears are furnished with levers resting, on opposite sides, upon flexible element of beam force metre that doubles as aforesaid torque metre. Aforesaid electric contact heater allows both in series and parallel connection of specimens to power source.
EFFECT: higher accuracy.
