This Proto torque tester is a precision tool designed to ensure accurate torque measurements for various applications, ranging from routine checks to calibration needs. With a torque range of 60-600 ft-lb and an accuracy of 1%, it provides reliable performance in both clockwise and counterclockwise settings, making it versatile for testing all types of torque wrenches. The tester features multiple operating modes, including Track Mode, Peak Hold, and First Peak, which accommodates different wrench styles and allows for quick assessments or detailed evaluations.N.I.S.T. traceable certification accompanies each unit, ensuring that the tool meets high standards of accuracy over its broad measurement range, which operates effectively from 10% to 100% of full scale. It is powered by a standard 9V battery, providing up to 50 hours of operation, and can be conveniently adapted with optional accessories like an all-steel stand for stable use. The inclusion of both male and a female-to-female square drive adapter extends its functionality, making it an essential tool for professionals who require precision and reliability in their torque measurements.
