Hardness TesterSelection Chart | | | Our product line consists of varioustypes of durometers applicable to specific materials as indicated in the chart above.
Type A Durometer (ASKER A type), conforming to JIS K 6235 is themost popular type of durometer for measuring rubber hardness.
However, verification is recommended because a significantdifference is estimated to be the largest when a durometerindicates measurement values from 10 to 90 points.
For hard specimens for which Type A Durometer readings indicatemore than 90 points, measurements should be undertaken using theType D Durometer (ASKER D type). However, for soft specimens withmeasurements of less than 20 points, the ASKER C type or Type EDurometer (ASKER E type) should be used. The most importantconsideration in using durometers is to select the correct type forpurposes of measurement according to the specimen. |

| Option |
|
| | | | Two-pointer type (max-hand andactive hand) of Rubber Hardness Tester The stationary set hand (max-hand) makes the maximum value easierto read and allows the creep characteristics of a specimen.
Accurate measurement is made possible for specimens* for whichstress relaxation occurs over time or for specimens for which it isdifficult to take readings from the front.
*Materials for which the reading decreases immediately after theindentor has been pressed against the surface. |
| | | | | Constant Loader forDurometer
· | Constant loarder assures uniform test pressure eliminatingfalse readings due to differences between operators in measuring byhand. | · | High accuracy and repeatability of the hardness readings areassured by the flexible joint function. |
