Product Description

Shore ceased all production operations in 2012 and their products are no longer available. CCSi continues to support Shore equipment in regard to service, calibration and ISO/IEC 17025 certification.


The Shore® Constant Load durometer is designed to minimize the variations in test determinations by the inconsistent application of force when the instrument is used manually.

This durometer incorporates a larger presser foot (51 x 51 mm) for stability and a mass intended to produce a more consistent application of force.

It is designed for testing specimens having minimum dimensions of 51 x 51 mm, the opposite sides of which are flat and parallel. It may be manually applied or, for better repeatability and accuracy, mounted on a Shore® Operating Stand.

Please refer to the Shore® Durometer Selection Guide for an explanation of Shore® model, type and scale designations, as well to assure the proper selection of the Shore® durometer to suit your specific application.
