Below is a list of Torque Tester manufacturers from Norwood, Massachusetts. Torque testers are devices that measure and calibrate torque in tools, parts and equipment. They typically determine the maximum and minimum torque as well as the accuracy of the actual output as compared to the displayed amount. Though similar in purpose, they are different from dynos. Some have a temperature compensation feature that prevents a mistaken reading by accounting for the effect increasing or decreasing temperatures can have on a measurement.
