Applications Calibration of Impact tools Calibration oil pulse tools And also any type of manual wrenches Importance of Torque tool calibration: Controlling torque of a torque tool is important for companies to ensure proper torque being applied for their product s quality, safety and reliability and also to Maintain gauge requirements associated with ISO 9001 quality standard. By regular calibration one can assure that the accuracy of a torque tool is within the specified tolerances and maintain continuous quality standards in the assembly process. The Calibration ensures the performance of a torque tool and indicates the need for any adjustment. Also the potential tooling problems can be identified before they arise, either due to tool wear and tear or broken components. Hence, the torque tool calibration equipment plays an important role along with traceability to assure that all measuring results are in accordance to the National/international standards Features Unit OR The system consists of Torque Sensors, Digital Torque Display Digital display of Torque, Impact per minute/pulse per minute(for pulse tools), Or Digital display of Torque + Impact per minute + Free Speed Measurement Or Digital display of Torque + Impact per minute + Free Speed Measurement + Pressure, Free speed measuring fixture depending on the customer requirement. Rigid table to mount the Torque sensor, Display unit and Free speed measuring unit Optional
