Rockwell Hardness Tester DK8000

[Specifications]:
· A closed-loop control;
· With traditional weight;
· Highly accurate;
[Rockwell Hardness Tester DK8000 Product details]:
 Product Specification:

New features:
  • The test force are applied via a closed-loop control unit with a load cell, a DC motor and an electronic measurement and control unit instead of traditional dead weights. The result is highly accurate measurements at all test loads up to 0.5%.
  • PnP tech. Simple plug - and - play tech allows for much more quick and easy installation than traditional weights type machine.
  • Motor driving lifting mechanism make the testing more easily. Just press START key once, whole process will be finished automatically. No matter the size of the sample, the position of the sample, the distance between the indenter and sample surface. The sample will be auto-lifted to approach the indenter and finishing testing automatically.
  • More testing precision than handle wheel lifting type machine which effected by human factors.
  • More long nose make more testing space up to 300mm*220mm( vertical*throat)
  • Integrated casting body with more wide basement leads to permanent stability.
  • With integrated micro-printer.
 
 Basic functions:
  • Regular Rockwell hardness tester for metal and plastic material.
  • Horizontal protrudent Indenter Design, suitable also for internal and external testing.
  • Testing on Surfaces difficult to reach. Testing internal surface of rings and tubes.
  • Provided with many features such as high measuring precision, wide measuring range with 15 Rockwell scales.
  • The tester is suitable for testing of carbon steel, alloy steel, cast iron, non ferrous metal.
  • Automatic testing cycle: Approaching, pre-loading, loading, dwell, unloading, result reading will be finished automatically.
  • Measuring results digitally displaying and can be printed, or transmitted to external computer automatically by USB port.
  • Test HR value can be convert to the value of HB, HV, HK and σb value.

  • The tester meets all the following standard such as ISO 6508-2, ASTM E18.
