Electronic tensile force measuring device for measuring thin wires, strands and textile materials. Equipped with rollers of 10 mm (or 11 mm zylindrical roller 5 to 45 mm wide) diameter, also suitable for measuring fiber optic cable. Direct reading of measured tensile force. Display damping can be activated, i.e. stable and smooth display even during fluctuating tensile forces. At the push of a button the last indicated measuring value will be held.
