Description 
The ring dynamometer is constructed of a steel load ring with fully jeweled precision dial indicator to show the deflection under load. To assure consistent accuracy, each dial indicator used has passed a rigid screening process. The dial reading is easily translated into pounds by referring to a calibration report included with each instrument. Standard ring dynamometers are calibrated at loads from one-tenth of capacity. If specified, ten special loads can be calibrated in lieu of the standard loads.
