Digital hardness tester with integrated printer
HardyTest D700
Digital hardness tester HardyTest D700 for 6 external impact device types and integrated printer
The hardness tester HardyTest D700 measures the hardness of a large number of materials in six different hardness units. A selection of six impact device types allows the hardness measurement of specific material shapes in different hardness levels. In addition, the hardness tester is equipped with an integrated printer and the ability to transfer data to the PC.
The hardness tester HardyTest D700 along with its brother the HardyTest D600 belong to the high class in hardness measurements. It was developed to meet all requirements in professional hardness testing.
The HardyTest D700 is applicable for almost all hardness measurements on ferrous and non-ferrous metals. For use in the power plant industry, petrochemicals, apparatus, vehicle and mechanical engineering, quality control, steelworks, and more, the hardness tester HardyTest D700 has proven to be excellent.
