RDC-1 Durometer Calibrator

Click images to enlarge.
The RDC-1 durometer calibrator was designed to help durometer users obtain in-house calibration ability. The calibrator comes complete with weights for calibrating springloads of gauges in the A, B, C, D, DO and O durometer scales. It also includes an adapter which gives the RDC-1 the ability to calibrate durometers from many different manufacturers. The RDC-1 is a great way for durometer users to cut the costs of sending durometers out for calibration at the recommended yearly intervals.

From the beginning, the RDC-1 calibrator was designed to be simple to use. Unlike a conventional scale, it doesn't require the fabrication on an exotic fixture to hold the gauge, and the user doesn't have to perform any complicated calculations to determine if a gauge is in calibration. With the RDC-1, simply secure the gauge in the clamp and slide the weight to the appropriate point on the scale, if the gauge reads within +/-1 of the point indicated on the scale, it's in calibration.

The RDC-1 offers quality unparalleled by any other. With its thick steel base, oversize stainless steel column, and thirty pound weight, the RDC-1 is the sturdiest calibrator made. All components are precision CNC machined to exacting tolerances, and then plated or painted to insure long life. The RDC-1 comes to you fully calibrated with documentation traceable to NIST. It also comes with instructions and technical notes covering specifics about durometer calibration. The RDC-1 calibrator is made and assembled in the U.S.A.
