This affordable, adaptable semi-automatic hardness tester is capable of effortlessly examining materials such as O rings, seals, and tube-shaped elastomers. This automatic hardness tester is designed for soft elastomers with a thickness of up to 0.6mm, which can be conveniently examined using interchangeable measuring instruments for procedures IRHD M and IRHD N, yielding very accurate results. This hardness tester digital display ensures that measurements are easily readable, and the device adheres to international standards in terms of contact pressure and measurement time, ensuring hardness testing compliance with ASTM D1415, DIN ISO 48-2, and NF ISO 48 hardness standards.
The Hardness Tester IRHD Compact III is equipped with a digital hardness tester interface, capable of storing up to 300 test results, making it a hardness tester with memory that meets various operator needs. This indentation hardness tester is specifically designed for rubber hardness testing and plastic hardness measurement, ensuring accurate results across different materials. The interchangeable probes allow for flexibility in testing various elastomers, including the soft rubber hardness tester application. Additionally, the device supports micro IRHD testing and normal IRHD measurement, providing comprehensive data for elastomer testing. The optional “BareissOne” software is a highly beneficial, Windows-based program that provides functionalities such as data recording, article administration, graphical presentation of data and hardness curves, statistical assessment, and further analysis of the observed values. This enhances the functionality and usability of the hardness tester, making it a comprehensive tool for precise and efficient hardness testing.
