Gurley Precision Instruments
Bending Resistance / Stiffness Testers All Genuine GurleyTM bending resistance/stiffness testers are based on the same physical principle. each instrument consists of a balanced pendulum or pointer which is center-pivoted and can be weighted at three points below its center. The pointer moves freely in both left and right directions on cylindrical jewel bearings which make the mechanism highly sensitive even to light-weighted materials. There are two versions available. Flat sheet. Tubing. A sample of a specific size is attached... (read more) -
