ASKER Durometer Type CS

The ASKER Durometer Type CS is designed to decrease false readings of measurements for polystyrene foam by simultaneously deforming multiple granular foams.

The larger indentor and stronger spring than those of the ASKER Type C enable the stable measurement of large-sized granular particles such as polystyrene foam.

Hardness Tester Selection Chart

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 6253-3 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.

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.
