The RDC-1 durometer calibrator is designed to measure the spring force of A, B, C, D, DO and O durometers. It's single beam design has notches for testing at 10 point intervals from 0-100 units. Heavy duty construction and adjustable leveling feet help ensure accurate measurement.

The RDC-1 includes mounting adapters for Pencil Style and AD/DD-100 Models. Adapters for other brands are also available, please inquire for details.

NOTE: The RDC-1 calibrates durometer spring force. Full calibration requires inspection of the indentor shape and extension length. This requires an optical comparator or similar magnifying device offering at least 20x magnification per D2240 (50x for type M).
