Shore hardness testers - analog and digital

Tried, tested and up to the minute

These Shore electronic hardness testers are used for determining the hardness of plastics and rubber to ISO 7619-1, ASTM D2240, ISO 868, NFT 51109 and BS 903 Part A26. For on-site testing on the product, analog versions with and without drag-pointer are available. The instruments with drag-pointers simplify testing, particularly in difficult-to-access locations, as the pointer still indicates the measured value after the test. Hardness value determination after dwell times of 3 seconds (ISO 7619-1) and 1 second (ISO 868) can be accommodated with digital hardness testing instruments.
Analog Shore hardness tester ISO 7619-1, ASTM D 2240

Typical applications

  • Soft rubber, elastomers and natural rubber to Shore A
  • Harder elastomers, plastics and rigid thermoplastics to Shore D
  • Soft elastomers and textile fabrics to Shore 0
  • Expanded rubber, sponge rubber and foam rubber to Shore 00
  • Harder elastomers than Shore A as per Shore B
  • Medium hard elastomers to Shore C

Additional features of analog hardness testers

  • Fast, easy testing: the hardness tester is pressed smoothly against the specimen with the prescribed contact force until the presser foot is firmly seated. The hardness value is read off three seconds (ISO) or one second (ASTM) after firm contact is achieved between the presser foot and the test material. The hardness value can also be read off after a longer contact period in the case of materials with significant flow-properties.
  • Zwick Shore hardness testers feature a round, anti-glare scale (graduated from 0 to 100 Shore) with precise measured-value display.
  • Hardness testers (for Shore A, D, B, C, 0) are available with or without a drag-pointer. The drag-pointer makes it easier to read off the maximum value and enables determination of the flow properties of the material during a defined period.
  • A practical carry-case protects the device from damage and dust.
  • The “Zwick 7206 test device with load-weight” option is suitable for analog Shore hardness testers (Zwick 3114 to 3117). The test device ensures that the hardness tester is exactly perpendicular to the specimen surface, leading to a significant reduction overall in measured-value scatter during hardness tests and is recommended for laboratory tests, as test-procedure repeatability is considerably improved if operator influence is eliminated. Interchangeable load-weights equivalent to 10 N (Shore A), 12.5 N and (optional) 50 N (Shore D) compressive force ensure uniformly consistent contact force.
  • To maintain accuracy in your hardness testers we supply rubber test sheets, test rings for 40 and 60 Shore and a test device to verify spring load characteristics.

Additional features of digital hardness testers

  • Hardness testing can be carried out in both vertical and horizontal orientations, on-site or at a fixed location. With digital hardness testers, the differing times after which measured values are to be determined (ISO specifications) can be input.
  • The testers consist of a handy cylindrical measuring head with integrated digital electronics.
  • Their low weight, compact dimensions and rechargeable battery operation make them suitable for portable use or for fixed laboratory testing (optional test device).
  • The compression spring is integrated into the measuring head in such a way that the contact ring allows accurate parallel positioning of the hardness tester on the specimen, eliminating measurement errors.
  • The end of the test time is indicated by visual and audible signals and the measured value is automatically shown on the display. This value can be transmitted to a PC by means of the testing software via RS232 interface for processing and archiving.
  • The tester always displays the current measured value. Up to 300 hardness values can be stored. If a significant length of time elapses without a test being performed the instrument will switch to standby mode.
  • The optional test device with load weight is suitable for Shore A and D digital hand-held hardness testers (Zwick 3130/31). It ensures accurate positioning of the hardness tester at right angles to the specimen surface, leading to a significant overall reduction in measured-value scatter. The reproducibility of the test procedure is considerably improved by the elimination of operator influence. Use of a test device is therefore recommended for laboratory tests.
