Durometers feature portable design, ease of operation, and non-destructive measurement. They are heavy-duty and well-made with high repeatability. The measurement of hardness is an essential factor for determining the characteristics of various rubber, elastomers and plastic products. One of the most important steps in using a hardness tester is to select the optimum type from the various types available based upon different material hardnesses. The measurement scale is 100 points with an accuracy of ± 1 point.
