Digital Vickers and Knoop Hardness Tester

RoboTest Micro Hardness Tester RHD-1000/2000 series used to determine micro hardness of finished surface of small-size or sheet-like parts, micro hardness of superficial layers such as electroplated, carburized and nitride layers, and micro hardness of brittle materials such as agate, ceramics and other non-metallic materials. RH-1000/2000 series can be also used to examine and take photograph of microstructure of materials and to determine micro hardness of the phase structure for analytical purpose.

►  Digital Eyepiece Micrometer

►  Innovative design of control buttons and LCD display.

►  Auto motorized turret.

►  Easy to set and visualize hardness scale (HV or HK)

►  Selection of force unit (gf or N) and force duration

►  Adjustment of the brightness of illuminating lamp

►  Built in printer

►  Automatic load control
