Proving Rings for Calibration

High-accuracy Proving Rings for Calibration in Bangladesh. Ideal for calibrating testing machines, load frames, compression machines, and force measurement systems in geotechnical and civil engineering laboratories.

Load Rings, often referred to as proving rings, are manufactured from high-strength aluminum alloy with repeatable elastic deformation characteristics and are used to determine force measurements. Loads are measured with an accuracy of ±0.5% using the included mechanical dial indicator with 0.0001in resolution. A calibration chart to derive force values based on ring deformation is also included.

Load Rings are available in eight different capacities ranging from 250 to 10,000lbf and have a mounting hole size of 1/2inx20tpi, making them compatible with Gilson and other manufacturers' load frames and direct shear units.
