FEATURES

Digital / Dial Durometers are suitable for testing the nature of the following materials -natural rubber, neoprene, polyesters, P.V.C., leather, nitrite rubber, wax, vinyl, cellulose acetates, glass polystyrene, etc.

         Technical Data

  • Designed in accordance with the ASTM D 2240, ISO868, ISO 7619, DIN 53 505, JIS K 6253, and JIS K 7215 specifications.
  • Units are available in both Shore A and Shore D scales, and will test a wide variety of applications.
  • The Digital Durometer is provided with data hold function, permitting the operator to make an error-free reading on the LCD screen.
  • The Dial Durometer is provided with a peak retaining hand for error-free reading.

    Testing stand applications
    These stands are used to mount Durometers. They allow constant-pressure hardness measurement by pressing the Durometer vertically on a work piece.

  • Anyone can perform repeatable hardness measurement due to fewer possibilities of human error and measurement variations.
  • The supplied weights can be attached directly to a Durometer and allow constant-pressure hardness measurement of large samples for which a stand cannot be used.
  • The supplied weights are used for calibrating the spring tension of Durometers.

Hold function

Holds the display value at any time during measurement so that you can easily check the measurement result.
