Product Description

The Rex Model MSDD-4 Durometer features the Model DD-4 digital indicator and interchangeable “barrels” in ASTM D2240 Types (Shore scale) A, D, and OO.

Changing scales is accomplished by unscrewing one barrel and replacing it with another – no supplementary calibration or adjustments are necessary.

The indicator and barrels are made in the USA, and are calibrated to the ASTM-D2240 standard for durometer hardness testers.
