Description

If you’re in the market for a bench hardness tester, the NR3D from Ernst is difficult to beat. This Rockwell hardness tester also performs readings in the Brinell scale (HB 30 for steel; HB 10/HB 5 for light alloys and aluminum). Known for its precision and reliability, the Ernst NR3D is designed to test items with small to medium dimensions.

In addition to offering a Rockwell version, we also offer a Super Rockwell version, which is optimal for the control of plastics. Additionally, the NR3D does not have a penetrator or penetrator shroud, giving it the ability to measure smaller parts. This setup is also perfect for spheres or composite materials.
