Automatic O-Ring Hardness Tester

Our automatic modular hardness tester, DigiTest has already found great popularity in the market for its advanced technology, top quality and repeatability of the results that it provides to the plastics & rubber industry for hardness measurement in Durometer and IRHD scales.

Now the DigiTest has advanced to a modified version as an Automatic O-ring hardness testing system. The main reason for developing this system has been increasing customer demands who wanted to increase their efficiency and do in-line tests tests on O-rings in series of 50 to 100 rings within the measuring range of IRHD micro acc. to the standards DIN 53519 sheet 2, ISO 48, NFT 46003, ASTM D 2240 and BS 903 Part. A 26.

The most important advantage is that a larger quantity of tested samples provides a far more reliable results and better statement of the quality of the material.

The automatic tester allows the automatic test on O-rings of a cord diameter between 0,6 an 5 mm and an outer diameter up to maximum 30 mm.

O-rings of a bigger shape can be tested in single measurements. The O-rings are pushed on a bar magazine and are fed by an automatic sledge system. The centring device of the rings guarantees that they are tested at the highest position.
At the end of the measurement they are selected to be GOOD or BAD.

The tolerance limits of this function can be stored in the electronic unit so that O-rings of different cord diameters and outer diameters can be tested quickly and easily. For that purpose, the automatic tester can be adjusted to the different sizes without any problems.

Operators’ influences, which could affect the results, are eliminated because of the automatic operating cycle. Furthermore the operator has the possibility to perform other tasks during this automatic process.

You can observe the charge- and discharge characteristics of a sample within the IRHD range and transfer the data to a PC with the help of a suitable software.

The operating mode STANDARD GRAPH draws the flow curve of the IRHD measurement whereby you can observe the charge characteristics of O-rings.

The measured values can be logged or the corresponding curves can be drawn using a special software.
