The Imada E2 durometers now feature an environmentally friendly magnesium alloy housing. E2 durometers are quick and easy to operate with a high degree of repeatability. Optional peak indicators are available on each model.
Hardness is an essential characteristic of rubber, elastomers and plastic products. Select the optimum durometer type based upon material hardness. E2 models are available in Durometer Types: Shore A, D, E and Asker C Hardness.

As 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 materials hardness. Values are based upon a 100 point scale (accuracy 1 point).
