Asker hardness testers feature top design and precision manufacturing to bring you a reliable, highly accurate durometer.

Super EX durometers feature portability, ease of operation, non-destructive measurement and optional peak indicators. They are heavy-duty with high repeatability for plastic and rubber hardness testing.

Super EX models are available in Durometer Types: Shore A Hardness, Shore D Hardness and Asker C Hardness.

Hardness is an essential characteristic of various rubber, elastomers and plastic products. The first step in using a durometer hardness tester is to select the optimum type based upon the material hardness.

*Add ‘P’ to the model number to specify optional peak indicator, for example EXP-A.

EX durometer operationAs the durometer is pressed against the sample, the material resistance force and indentor spring load balance. The depth of the indentor is measured, which provides a measure of the material’s hardness. Values are based upon a 100 point scale (accuracy ±1 point). However, as time elapses the indicator will “creep” back so that a reading taken a few seconds after the indentor makes contact with the sample will be less than the peak reading. Asker durometers offer a peak indicator as an option to more closely monitor the difference between peak and “creep”.
