Features Indentor Height: 2.54mm Shape: Cylindrical Pressure foot An oval shaped pressure foot(50mm x 37 mm) in contact with a specimen allows a stable measurement by placing it onto the specimen. 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. Specification Indication range 0 point - 100 point (262 degree dial scale) Minimum indication 1 point (Accuracy : ±1 point) Indentor Design (mm) Height: 2.54 15 Dia. Cylindrical Spring Forces [mN(g)] 0 point: 980(100) 100 point: 1960(200) Central hole of diameter of Pressure foot Φ16 Pressure foot Dimension (mm) 50×37(Oval shape) Outer Dimension (mm) Approx. Width 50×Depth 37×Height 81 Weight (g) 300 Application Powder puff Option 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.
