  • Product description
  • Specifications
  • Full automatic/semi-automatic rockwell hardness tester of new upush-down intender adopt . advanced closed loop sensor control technology to realize automatic control and hardness testing process. Loading system use the high precision sensor and central controller forming a closed loop circuit to realize the continuous tracking and control burner process. Sounding system adopts high precision displacement sensor, which can obtain minimum hardnessvalue resolution 0.1 HR. The up –and- down motion of indenter can test hardness when object stage was fixed,. Fixed testing bench can eliminate coaxial error due to traditional lead screw rotating up and down, greatly improve the test precision and repeatability, also increases the stability and efficiency of the machine run.

     

     

    Features

    ● Strong rack construction, good rigidity .

    ● Full automatic closed loop sensor loading

    ● Test 15 kinds of Rockwell and 15 kinds of superficial Rockwell hardness scale .

    ● High accuracy and international contrast is less than 0.5 HR .

    ● New design, the push-down intender.

    ● High precision loading system, effectively avoid dynamometry overloading

    ● Can be retreated from function in fixed worktable automatically by the pressure head in and out of the last

    measurement

    ● Automatically promote the initial test load handpiece and automated load, can guarantee the load producing steadily
