Universal rebound hardness tester with robust metal (aluminium) casing and large memory
The dynaROCK II is a portable device for testing the hardness of materials. The measurement is implemented according to the Leeb hardness testing method. Using this method, most metallic materials can be measured within a large measuring range. For different applications, six impact device types are available. The type of the connected impact device is identified automatically.
Measurements can be made in any direction, even overhead (except the impact device type C). The hardness is displayed directly in the hardness scales HRB, HRC, HV, HB, HS or tensile strength (MPA; measurable only with the impact device types D, DC and G). A limit-value acoustic alarm facilitates the evaluation.
The dynaROCK II is provided with a measured value memory in which up to 500,000 measured values, with date, time and measuring parameters, can be stored. The readings are arranged in series of measurements. A series of measurements is an aggregation of several readings. In addition to ordinary measurement series, serial measurement series which consists of multiple subordinate measurement series, can be recorded. Saved series of measurements, including statistics, can be displayed, printed or copied to a USB flash drive at any time.
