DX 833: SHORE HARDNESS TESTER IN COMPLIANCE WITH ISO AND ASTM STANDARDS

The repeatability of digital Shore M/AM hardness tests for rubber and plastic par excellence

We personally projected DX 833 Shore hardness tester to perform Shore M and AM scales in a fully controlled manner: the test cycle is in fact electronic and automatic.

Suitable for all polymers, elastomers, rubbers and gel-like materials (such as plastics, soft rubber, medical items, paper and sponges) of small to medium size and complex geometries.

Full compliance with the international standards, including: ISO 48-48, ISO 868, ISO 21509 and ASTM D2240

Why choosing a stationary Shore hardness tester?

It eliminates human influence during the execution of the test, therefore ensuring greater accuracy of results.
Due to the correct perpendicularity and orthogonality of the indenter to the sample, which only a benchtop hardness tester or support can guarantee, the accuracy of the Shore hardness value is significantly improved (see ISO 48-4, part 4, § 6.3)

It maximises the reproducibility of measurements thanks to the electronic control of the probe descent speed: the DX 833 Shore hardness tester can in fact program values from 0.5 mm/s to 16 mm/s.
The load application time and speed are in fact two parameters that the ISO 48-4 standard identifies as contributing to the reproducibility error. This is why, it becomes essential to be able to control them electronically through the Shore hardness tester.

Thanks to the extensive kit of dedicated accessories, DX 833 can be used to perform Shore hardness gauges of objects with complex geometries.

Are you looking for other Shore Hardness scales according to ASTM D2240, ISO 48-4 and ISO 868?

Visit the page dedicated to Shore portable hardness testers. Wheter it deals with Shore A durometer or other scales, here you will find the solution you are looking for.
We are the only company in the Italian market that produces personally the entire range of Shore hardness tests in all Shore scales according to ISO 48-4, ASTM D2240, ISO 868 and ISO 21509. To have an optimal hardness measurement you have to choose the right shore durometer: Shore D durometer and A scale are not the only test methods that you should consider, since each type of polymer (soft rubber hardness or harder elastomers) demands a specific indentation hardness, and consequently a specific Shore durometer scales.

Shore durometers: regulatory transparency guaranteed

The decision to design a stationary digital durometer instead of a portable one has not been defined by chance. The standards for the execution of Shore hardness tests speak for themselves:

  • The ISO 48-4 standard recommends an application of 250 g for the Shore AM scale.The application of this force can hardly be guaranteed manually by using the durometer in portable mode.
  • The ASTM D2240 standard requires an exclusive use of the Shore M hardness scale with a stationary instrument to measure the Shore hardness units, as it calls for mandatory mm/sec control of the descent speed of the probe.

Choosing DX 833 durometer hardness means to rely on full regulatory safety with the full support of 100% Italian technology.
