| ASKER Durometer Type C1L |
 |
 |
The ASKER Durometer Type C, produced since 1956, is our original brand durometer, and is a de facto standard in the world for the measurement of soft rubber, sponges, etc.
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. |
|
| |  | | | Load Tester for Hardness Tester
| · | Tester to check load properties of the spring on a durometer | | · | Inspection is conducted at 2, 50, and 75 points respectively. |
