FIELD: measuring technique.
SUBSTANCE: device comprises vacuum chamber that receives a vertical thread-like specimen. The horizontal transparent cylindrical sleeve is secured to the vacuum chamber. The device also has a system for generating oppositely directed temperature gradient at a given point of the thread-like specimen for forming a creeping zone, mechanical lever whose one arm is set in the vacuum chamber and connected with the thread-like specimen and other arm is arranged along the axis of the transparent sleeve and has compensating weight, and optical lever. The device is provided with means for moving the compensation weight.
EFFECT: enhanced accuracy of measurements.
