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.
Capacities
100 to 300,000 pounds. Higher on special order in either compression or combination of tension and compression models.
Available in metric capacities also.
