DHV-2101

The DHV-2101 digital Vickers hardness tester makes use of large LCD to display measured data. Its operation interface is based on menu structure. The operator can select scale of hardness HV or HK on the operation panel. It supports the switch between various hardness numbers. The results can be automatically stored, processed or printed. Through the RS-232 interface, the hardness testing machine can be connected to a computer. With high digitization and automation, the hardness tester is capable of correcting value errors by means of software input.

Different from manual DHV-2101, the DHV-2102 belongs to digital hardness tester with automatic turret function. When measuring hardness, this non-destructive testing equipment supports the mutual switch between the indenter and objective lens. It is also provided with automatic positioning testing point function.
