THVS-2D型自動轉塔數顯顯微硬度計

Main characteristics:
　　●The instrument is well designed in the optical、mechanical and electric parts and hence produces very clear profiles.
　　●The illumination is adjustable and the light may go off automatically for the selfprotection.
　　●The numerical control tube screen can directly indicate the diagonal length of the indentment,the hardness value,the test force,the dwell time,and the number of the tests made.
　　●The instrument can trace and position the automatic tower with hight precision,completing the whole procedure of the objective→the loading of the carriage→the dwell of the carriage→the unloading of the carriage→the objective.
　　●The instrument has a place for the installment of CCD camera.
