Digital Vickers and Knoop Hardness Tester (Auto Stage)

RoboTest RHD-1000/2000ASM Micro Hardness Tester with MH_VK_dS Picture Analysis System equipped with computerized measuring system, with auto-motorized turret of precision positioning. Tester measures HV hardness or HK hardness automatically or manually. The machine with the friendly menu combining with the convenience measuring way, reduced the artificial error, increase the accuracy of the measurement

►  Variety forms of Test report, (in simple form, in Word form and in Excel form).

►  The case depth curve is obtained easily.

►  Hardness conversion between 15 hardness scales is provided Based on different materials and in accordance with GB (ISO) and ASTM.

►  Hardness correction on curved surfaces (spherical, cylindrical, either convex or concave).

►  Hardness calibration with Standard digital scale or hardness block.

►  Picture of user-specified magnification can be provided easily.

►  With a Step-motion stage of high accuracy.

►  Both the tester and the Step-motion stage are controlled by the MH_VK_dS software
