ASKER DUROMETER HARDNESS TESTER
HIGH PERFORMANCE X SERIES
Durometer Hardness Shore A Normal Rubber
Durometer Hardness Shore D Hard Rubber and Plastics
Durometer Hardness Shore C Soft Rubber and Sponge
Durometer Hardness Shore F Urethane foam, Sponge and polystyrene foam
As the hardness tester 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 ±.75 point). However, as time elapses the indicator will "creep" back so that a reading taken a few seconds after the tester makes contact with the sample will be less than the peak reading. The optional peak indicator helps to more closely monitor the difference between peak and "creep" in hardness tests.
Common Hardness scales :
Model X-A Shore A Hardness - Normal Rubber
