Ernst NR3D Economical Regular & Superficial Rockwell Hardness Testers

The NR3D Rockwell Tester is a sturdy, cost effective Rockwell Tester that is able to operate accurately even in the Superficial Rockwell test range, unlike many other lower cost testers. The unit comes with either a regular or superficial test head or both and the test heads can be swapped in a minute.

Features:

  • Uses interchangeable test heads for regular and superficial ranges
  • Digital display of Rockwell test results
  • The test head can be removed for factory calibration/repairs- very convenient for companies not located near a calibration/ service company.
  • Operates according to ASTM E18 or for light load Brinell and plastic hardness

the top of the test hand. Load is applied
with the lever on the side.
The tester is very precise and is
often purchased with the superficial
Rockwell tester head.
The tester is ideal for optional testing
of plastics, from rubber to acrylic plastic,
according to ASTM D-785.
