Digital Rockwell/Superficial Rockwell Hardness Tester


Model No. 900-384

Hardness Tester Features:

The test force is applied via a closed-loop control unit with a load cell, a DC motor and an electronic measurement and control unit that replace traditional dead weights. The result is highly accurate hardness test measurements at all test loads up to 0.5%.

Simple plug - and - play tech allows for much more quick and easy installation than traditional dead weight type machines.

Extended dolphin nose allows vertical hardness test height of 11.8” and throat depth of 8.6”.

Built-in micro-printer.


Hardness Tester Basic Functions:

  • Twin hardness tester --Regular Rockwell & Superficial Rockwell hardness test for metal and plastic material.
  • Horizontal dolphin nose Indenter is suitable for internal and external hardness testing.
  • Rockwell Hardness Testing on Surfaces difficult to reach. Hardness Testing internal surface of rings and tubes.
  • Provided with many features such as high measuring precision, wide measuring range with 30 Rockwell scales.
  • The Rockwell hardness tester is suitable for testing of carbon steel, alloy steel, cast iron, non-ferrous metal.
  • Measuring results digitally displayed and can be printed with its built-in thermal Mini-Printer.
  • Test Rockwell value can be converted to the value of HB, HV, HK and σb value.
  • The tester meets the following standards: ISO 6508-2, ASTM E18.
