• Repeatability within 0.2% of indicated load.
• Accuracy within +/-1% of indicated load.
• Factory calibrated.
ELE Proving Rings are available in the range of 450 lbf (2 kN) to 11,200 lbf. (50 kN). Both analog and digital models are available. The repeatability of all models of Proving Ring is within 0.2% of the indicated load and the accuracy is +/- 1% of the indicated load over the upper 80% of the working range at the calibration loads. The change of "no load" reading during calibration is less than 0.1% of the deflection under full load.
All ELE Proving Rings are calibrated in kN and supplied with a calibration chart for conversion to lbf. and kgf.
