Main features:
HV-50D adopts the 8-inch touch screen display and the operation interface adopts the menu type structure. The hardness scale HV or HK can be selected on the operation panel. The test hardness value is calculated and displayed automatically. Various hardness values can be converted to each other. The brightness of the light source can be adjusted without charge.
Single objective, can be calibrated according to standard hardness block or length scale to make the hardness value more accurate to meet the requirements。
With digital encoder's eyepiece structure, the touch screen displays the hardness value and D1, D2 value directly。
