ASKER Durometer Type CSC2

The ASKER Durometer Type CSC2 for ultra soft (low hardness) and spongy surface materials than those covered by the measuring scope of ASKER Type C and C2, such as soft rubbers, rubber rolls, etc.

It is suitable for foam materials such as urethane foam,

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.

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.
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.
