DUROMETER REPAIR, CALIBRATION AND CERTIFICATION
Any e2000 Millennium Style Durometer can be made as an "R" designation. The "R" designation specifies a presser foot diameter of 18 Â± 0.5mm (0.71 Â± 0.02in) in diameter, while the spring forces and indenter configurations remain the same. Please specify the "R" Type when ordering. US Patent D436,874
