China Digital Hardness Tester for Metal Hardness Testing

Touch Screen Digital Rockwell Hardness Tester
DigiRock-DR3

Introduction
Half automatic hardness tester except loading initial force and change force knob. Operation is very convenient and fast.
Color touch screen, displays loading force, indenter type, dwell time, and conversion scale.
Motorized control loading, dwell and unloading, eliminates error by manual operation.
Builtin micro processor auto compute max, min, mean and deviation value, resolution is 0.1HR, largely improve accuracy.
Auto hardness conversion to others scales, no need to check table and improve working efficiency.
Support Multiple languages, English, Turkish, German, etc. Convenient for local customers operation.
With 2000 single testing results and 1000 group results. Reviewing results and analysis.
Optional blue tooth mini printer is available.

Application
Rockwell B Scale HRB: Copper alloys, soft steels, aluminum alloys, malleable iron, etc.
Rockwell C Scale HRC: Steel, hard cast irons, pearlitic malleable iron, titanium, deep case hardened steel, and other materials harder than B100.
Rockwell A Scale HRA: Cemented carbides, thin steel, and shallow case-hardened steel.

Principle

The Rockwell test consists of measuring the additional depth to which a carbide ball or diamond penetrator is forced by a heavy (major) load beyond the depth of a previously applied light (minor) load (SET point).
The minor load is applied first and a SET position is established on the dial gauge or displacement sensor of the Rockwell tester. Then the major load is applied. Without moving the piece being tested, the major load is removed and, with the minor load still applied, the Rockwell hardness number is automatically indicated on the dial gauge or digital display.
The diamond penetrator is used for testing materials such as hardened steels and cemented carbides. The carbide ball penetrators, available with 1/16 inch, 1/8 inch, 1/4 inch, and 1/2 inch diameter, are used when testing materials such as steel-copper alloys, aluminum and plastics to name a few.
Rockwell testing falls into two categories: Regular Rockwell testing (e.g., C and B scales) and Rockwell superficial testing (e.g., 30 N and 30 T scales).
High Rockwell hardness numbers represent hard materials and low numbers soft materials.
When selecting a hardness tester for your application, it is important for you to consider the following:
A, Choose the correct test method based on the application.
Plan to use the highest test force and largest indenter possible. Consider the effects of the shape and dimensions of your test sample.
B, Verify the test results meet your requirements for accuracy and repeatability. There are significant differences between levels of performance within each classification of tester. A difficult job on one tester could be very simple and fast on another.
