Abstract: The apparatus, system, and method provides an instrumented container with a contour similar to that of a production container which includes two portions spaced apart and joined by a torque sensor. The instrumented container also includes a processor which directs the periodic sampling of data measured by the torque sensor during the capping process, and a memory which stores a plurality of data values. The apparatus, system, and method provides a reusable instrumented container form to which a portion of an actual production container may be attached. The instrumented container is indistinguishable, for purposes of the capping line, from a regular production container. It may thus be used to test individual spindles, randomly test application torque, verify set application torques, and provide accurate information as to the impact of a particular dye or other variable on bottle capping.
