The NB-3010 is an ideal solution for lab and medium volume Brinell testing applications. This tester is used for determining the Brinell hardness of un-quenched steel, cast iron, nonferrous metals and soft bearing alloys. The NB-3010 measuring range is 8 – 650 HBW using a tungsten carbide ball indenter. The NB-3010 applies precise loads using a deadweight design. A pneumatic cylinder ensures that the load descends smoothly without an impact effect, and that the deadweights return after the test. A 60 psig air regulator using clean, dry air is required.


Deadweights are used for applying up to eight different loads from 62.5 kgf to 3000 kgf. The NB-3010 also features a semi-automatic test procedure which is easy for the operator. The operator simply raises the elevating screw until the specimen makes contact with the indenter. At the press of a button, the load is applied and removed after a pre-defined dwell time. Time-at-loads of 12-, 30- and 60-seconds are permitted and each time period has a dedicated pushbutton further simplifying operation.

Special Features:

  • Simple-to-Use, Semi-Automatic Control

  • Pushbutton controls ensure proper loading and dwell time

  • High Accuracy Dead Weight Design

  • Precision dead weights apply load automatically without impact effect. Requires minimum operator monitoring

  • Economically priced, yet rugged. High-quality materials and construction

  • Certified and ready to use
