1. HBRV-187.5D Digital Display Motorized Brinell Rockwell & Vickers Hardness Tester has 8-inch touch screen intuitive display and single-chip microcomputer control system, which can realize man-machine dialogue and automatic operation. It has high test accuracy, simple operation, high sensitivity, convenient use and stable display value. The electronic closed-loop control applies the test force; it fully realizes the automatic operation of the test force application, removal, and direct display of hardness values.

Built-in printer, RS232 interface and USB interface, can realize data exchange between computer and hardness tester.
