For thickness measurements of very thin pieces of elastomers and O-rings with a thickness from 1 to 5 mm, the state of the art Micro IHRD hardness tester
is the best choice. This high accuracy system complies to international norms and standards, including DIN ISO 48, ISO 48 and ASTM D 1415.
The hardness tests are conducted with the use of the indentor, which has a maximum indentation depth of 0.3 mm. The whole Micro IRHD hardness system is controlled by software (MS-windows) that prevents operator errors. During the measurement process, 2 weights are automatically lowered and raised. As soon as the specimens are placed on the support table, the support table drives to the measuring head automatically. Then the minor load is lowered to the indenter, followed by the major load. After 30 seconds the Micro IRHD software measures the applied penetration of the indenter and converts it into Mirco IRHD units.
Further features of the Micro IRHD software include the measurement and output of the hardness value, graph, hysteresis, statistics, test reports and many more features. An ASCII-output file is provided. The data are transmitted to the IRHD controller, that is connected to the RS232 interface of the computer.
For specific measurements of O-rings and seals, the optional automatic O-ring center device is a helpful and accurate tool.
