The Mountz RDA Run Down Adapters for Torque Testers is designed to provide consistent and reliable torque readings when testing power driven torque control tools. Mountz RDA Run Down Adapters reduce the impact and irregular peaks that cause poor repeatability. Each Mountz RDA has an effective torque range and will provide repeatable torque data within that range if used correctly. The run down adapter is mounted in-line between the tool drive and transducer.
