HLT900-M Superficial Rockwell Hardness Tester

Test 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 replace traditional dead weights. The result is highly accurate measurements at all test loads up to 0.5%.
  • Simple plug - and - play tech allows for much more quick and easy installation than traditional weights type machine.
  • Manual handle wheel pre-load. Automatic main-load and testing cycle.
  • Extended dolphin nose allows verticaltest height of 300mm and throat depth of 220mm.
  • Integrated casting body with more wide basement leads to permanent stability.
  • RS232 and USB port to PC.

Functions:

  • Twin tester--Regular Rockwell & Rockwell Superficial hardness for metal and plastic material.
  • Horizontal dolphin nose Indenter is suitable also for internal and external testing.
  • Testing on surface difficult to reach. Testing internal surface of rings and tubes.
  • Provided with many deatures such as high measuring precision, wide measuring range with 30Rockerll scales.
  • The tester is suitable for testing of carbon steel, alloy steel, cast iron, non ferous metal.
  • Automatic testing cycle: Lifting of part, pre-loading, loading dwell, unloading, results 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 converted to the value of HB, HV, HK, and σb value.
  • The tester meets all the following standard such as ISO6508-2, ASTM E18.
