The P.A.T. line of Adhesion testing instruments gives the user all the versatility of advanced tensile testing machines in a hand held device. The P.A.T. line incorporates a self-aligning dollie and pull off apparatus. The P.A.T self alignment process stands alone with its patented test head that distributes force evenly and dynamically through the test specimen as the force is balanced continually between the four hydraulic legs until a material fracture occurs.
