Explanation/Annotation:For hardness measurement of constructive and carbon steels, non-corrosive of steels and alloys from non-ferrous metals in laboratory, shop and field conditions.
Detailed model description:Besides the hardness testing machine can be applied to checking of different materials of elastic properties with the help of subscales, provided in device.
hardness testing machine peculiarity:
- calibration against standards on hardness measurement of any nonporous materials (number of necessary standards 2. 9);
- automated correction of readings according to introduced in device of angle of incidence of transducer;
- condition "experiment" for laboratory studies;
- condition of oneshot or multiple measurements;
- checking of materials and products by hardness;
- inherent memory and exit on a personal computer (port of RS232);
- storage power supply and control of degree of battery discharge.
