Bareiss Automatic IRHD Compact III Tester for Application-Based Model Selection
These models are designed for intended for comparing closely related models before choosing a final configuration. It is especially useful for routine testing, inspection, and quality-control workflows, where the right choice often depends on differences in configuration, range, portability, and application fit.
Range of application IRHD M Hardness determination on hoses and tubes, O-rings, molded parts, reference plates, and sealing. Minimum material thickness of 0,6 mm
By means of interchangeable measuring devices for methods IRHD M and IRHD N, soft elastomers with a thickness of up to 0.6mm are easily tested with highly reliable results. The contact pressure and measuring time of this hardness tester are according to international standards. Hardness Tester IRHD Compact III has the capacity to store up to 300 test results and comes with interchangeable probes according to the requirements of the operator. The optional “BareissOne” windows-based software offers data logging, management of articles, display of graphics and hardness curves, statistical evaluation, and further analysis of the measured values.
Characteristics
