The Mechanical hardness tester for measuring hardness of soft elastomer, with drag needle for an accurate measurement of peak value The PCE-DX-AS hardness tester is used for measuring surface hardness (shore A) of hard rubbers and soft plastics. The shore hardness tester is composed of a single component with a measuring head and a 360º dial. To improve the readability of peak value, the device comes with a drag needle, that ensures the maximum reading can be captured. Once it has been measured, it can be reset to zero. With the PCE-DX-AS (A) model of hardness tester, you will always obtain the most accurate value of maximum pressure and also be able to accurately reproduce this value.
