| Pressure foot |
 | The Pressure foot in contact with the specimen is 44mm in width and 18mm in depth, wide enough to ensure accurate measurement.
Another type of durometer with an 18mm diameter pressure foot is available. In addition, the Longer Pressure Foot Type (DL Type) is applicable for measurement of narrow or concave specimens . |

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.
