A pneumatically powered impact system relieves the operator of repetitive lifting of the drop weight and improves the repeatability of the test. The operator simply moves a small ring to a preestablished position on the test tube to select the desired drop height. Pushing a button then initiates the system to automatically lift the weight to the exact selected position for sample removal and new sample replacement. By using a mechanical stop, the test eliminates any variation in the drop point by individuals releasing the weight by eye.
