The Bareiss Fully Automatic Durometer – Digi Test II is a sophisticated automatic hardness tester that uses automation to accurately measure the hardness of elastomers and foam materials. It is capable of measuring Shore, Micro, IRHD (international rubber hardness degree), and VLRH (very low rubber hardness). The Digi Test II, our advanced Shore hardness testing equipment, contains an electronic unit that functions as the central control of the system. It also displays user information about measuring time, measurement technique, and numerous selectable characteristics.
This elastomer hardness tester offers a distinct advantage over traditional hardness testers by enabling Shore durometer testing on both convex and concave surfaces. This is made possible by the use of automated surface detection technology, which is not available in conventional hardness testers confined to flat-surfaced samples. Furthermore, we have the capability to tailor the length of our indenter to precisely reach any desired location on the sample for measurement purposes.
The Digi Test II is ASTM D2240 compliant and adheres to the DIN ISO 7619 standard, making it suitable for various IRHD hardness measurements and soft elastomers hardness tests. Additionally, it meets the DIN ISO 27588 certification requirements, ensuring precise soft rubber testing. Bareiss provides a wide selection of basic sample holders and positioning devices and excels in tailoring holders to suit your specific goods.

Operating Procedure
The measuring equipment include Shore, A, B, 0, D, C, D0, 00, 000, 000S, Asker C, and CS.
1) When the electronic unit is turned on and connected to devices for shore D, C, D0, Asker CS, the display indicates the need to add more weights, and the loads are then applied appropriately.
2) The sample is positioned on the supporting table to provide adequate contact between the surface of the supporting table and the sample.
3) The reliability and precision of the results improve when the highest point of the sample is positioned below the indenter.
4) The supporting table is manually adjusted using a hand wheel to achieve a gap of 3mm between the indenter and the test specimen.
5) Depress the ‘START’ button to initiate the automated descent of the measurement apparatus onto the test specimen.
6) After the completion of the measuring period, the measuring equipment returns to its initial position and displays the measured value. At the same time, the data can be transferred.
Measuring device Shore, A/B/0:
1) The loading weight on this measurement instrument should be positioned in a state of unrestricted movement. To adjust it to the higher position, exert upward force and rotate in the opposite direction of the arrow.
2) It is important to ensure that the indenter is not visible during testing in order to allow for unrestricted movement of the loading weight.
Measuring device M Shore, A/B/0, M Shore D:
1) Loosen the knurled screw till the loading weight can travel without any obstruction.
2) It is important to ensure that the indenter is not visible during testing in order to allow for unrestricted movement of the loading weight.
The measuring equipment is called M Shore and it has three different modes: A, B, and 0. Additionally, it has a specific mode called M Shore D.
1) The screw with a textured surface on the pressure plate has to be loosened in order to allow the pressure plate to move without any restrictions.
2) It is important to ensure that the indenter is not visible during testing in order to allow the pressure plate to move freely.
