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.


This precision automated system is designed to produce readings to laboratory standards in a production environment and reduce the operator introduced error commonly associated with IRHD testing.

The DuroTronic™ 2000 IRHD instrument provides timed automatic operation with LCD readout. The Model 903/2000 may be interfaced, using the integral RS-232C connection, to a PC or LAN (local area network) for convenient data transfer.

The standard test system is designed to comply to ASTM D1415, “Standard Test Method for Rubber Property — International Hardness” (2.5 mm indentor), as well as ISO 48, Type N. The IRHD method measures the indentation of a spherical indentor in elastomeric materials under precise load and time parameters.

The measurement is accomplished by applying a minor load to the indentor, which establishes the ‘0’ IRHD position. A major load is then applied, the indentor penetration is again electronically measured and the IRHD hardness measurement of the test specimen is displayed.
