| Pressure foot |
 | The Pressure foot in contactwiththespecimen is 44mm in width and 18mm in depth, wide enoughtoensureaccurate measurement.
Another type of durometer with an 18mm diameter pressurefootisavailable. In addition, the Longer Pressure Foot Type (DLType)isapplicable for measurement of narrow or concavespecimens. |

| HardnessTesterSelection Chart |  | | Our product line consistsofvarioustypes of durometers applicable to specific materials
as indicated in the chart above.
Type A Durometer (ASKER A type), conforming to JIS K 6235isthemost popular type of durometer for measuringrubberhardness.
However, verification is recommended becauseasignificantdifference is estimated to be the largest whenadurometerindicates measurement values from 10 to 90 points.
For hard specimens for which Type A Durometer readingsindicatemorethan 90 points, measurements should be undertakenusing theType DDurometer (ASKER D type). However, for softspecimenswithmeasurements of less than 20 points, the ASKER C typeor TypeEDurometer (ASKER E type) should be used. Themostimportantconsideration in using durometers is to select thecorrecttype forpurposes of measurement according to thespecimen. |

|
|  | | | Two-pointer type(max-handandactive hand) of Rubber HardnessTester
The stationary set hand (max-hand) makes the maximum valueeasiertoread and allows the creep characteristics of aspecimen.
Accurate measurement is made possible for specimens*forwhichstress relaxation occurs over time or for specimens forwhichit isdifficult to take readings from the front.
*Materials for which the reading decreases immediatelyaftertheindentor has been pressed against the surface. |
