ASKERDurometer Type DASKER橡膠硬度計

The Type D Durometer forhard rubber (high hardness) and plasticsASKER橡膠硬度計

Used world-wide for measuring hard rubbers and plastics, andspecified in the standards of JIS K 6253, ASTM D 2240, ISO 7619,DIN53505, etc.

Features

Indentor

Height: 2.50mm Shape: Sharp ConePoint

Pressure foot

The Pressure foot in contact with thespecimen is 44mm in width and 18mm in depth, wide enough to ensureaccurate measurement.

Another type of durometer with an 18mm diameter pressure foot isavailable. In addition, the Longer Pressure Foot Type (DL Type) isapplicable for measurement of narrow or concave specimens .

Hardness TesterSelection Chart

Our product line consists of varioustypes of durometers applicable to specific materials
as indicated in the chart above.

Type A Durometer (ASKER A type), conforming to JIS K 6235 is themost popular type of durometer for measuring rubber hardness.

However, verification is recommended because a significantdifference is estimated to be the largest when a durometerindicates measurement values from 10 to 90 points.

For hard specimens for which Type A Durometer readings indicatemore than 90 points, measurements should be undertaken using theType D Durometer (ASKER D type). However, for soft specimens withmeasurements of less than 20 points, the ASKER C type or Type EDurometer (ASKER E type) should be used. The most importantconsideration in using durometers is to select the correct type forpurposes of measurement according to the specimen.

Option

Two-pointer type (max-hａnd andactive hand) of Rubber Hardness Tester
The stationary set hａnd (max-hand) makes the maximum value easierto read and allows the creep characteristics of a specimen.

Accurate measurement is made possible for specimens* for whichstress relaxation occurs over time or for specimens for which it isdifficult to take readings from the front.

*Materials for which the reading decreases immediately after theindentor has been pressed against the surface.

Constant Loader forDurometer

·	Constant loarder assures uniform test pressure eliminatingfalse readings due to differences between operators in measuring byhand.
·	High accuracy and repeatability of the hardness readings areassured by the flexible joint function.

Indentor ExtensionTester

·	The gauge to check the indentor height on a durometer and thereading indicator mechanism.
·	Inspection is conducted at 2, 50, and 100 pointsrespectively.
