ASKER Durometer Type EL |
|
|
The ASKER Durometer Type E for soft rubber (low hardness), as specified by JIS K 6253 and ISO 7619. The application is the same as the standard ASKER Durometer Type C
Widely used for measuring soft rubber, sponges, and other foam elastomers, as well as rolled-threads, -films and textile windings (yarn packages). |

Hardness Tester Selection Chart | | | Our product line consists of various types of durometers applicable to specific materials as indicated in the chart above.
Type A Durometer (ASKER A type), conforming to JIS K 6235 is the most popular type of durometer for measuring rubber hardness.
However, verification is recommended because a significant difference is estimated to be the largest when a durometer indicates measurement values from 10 to 90 points.
For hard specimens for which Type A Durometer readings indicate more than 90 points, measurements should be undertaken using the Type D Durometer (ASKER D type). However, for soft specimens with measurements of less than 20 points, the ASKER C type or Type E Durometer (ASKER E type) should be used. The most important consideration in using durometers is to select the correct type for purposes of measurement according to the specimen.

| Option |
|
| | | | Two-pointer type (max-hand and active hand) of Rubber Hardness Tester The stationary set hand (max-hand) makes the maximum value easier to read and allows the creep characteristics of a specimen.
Accurate measurement is made possible for specimens* for which stress relaxation occurs over time or for specimens for which it is difficult to take readings from the front.
*Materials for which the reading decreases immediately after the indentor has been pressed against the surface. |
| | | | | Constant Loader for Durometer
· | Constant loarder assures uniform test pressure eliminating false readings due to differences between operators in measuring by hand. | · | High accuracy and repeatability of the hardness readings are assured by the flexible joint function. |
|
| | | | | Indentor Extension Tester
· | The gauge to check the indentor height on a durometer and the reading indicator mechanism. | · | Inspection is conducted at 2, 50, and 100 points respectively. |
|
