The hardness tester is intended for measuring the hardness of metallic materials by the following methods:
Rockwell – according to the standard STN EN ISO 6508
Brinell – for ball with diameter Ø 2.5 mm, according to the standard STN EN ISO 6506.
The machine control computer allows
- for the selected measuring method, select the indenter, main load and weight
- corrections for uneven surfaces
- communication language setting: Slovak, Czech, English and German
- to set date and time
- to define measurement time
- to determine the strength and also the depth of the indent
- conversion for other scales according to the standard DIN 50 150
- to transfer data to PC
- statistical processing of results
- direct print of protocols
- to control the sensor settings
