Basic machine design & operation similar to Al B-3000(H). In addition, an ‘optical device’ with 14 x Magnification provided in front to project dia of ball impression on glass screen with a micrometer measuring system with 0.01 mm accuracy. The indenter sweivels & projects dia of ball impression immediately after unloading operation which avoids additional time for measurement of ball impression. This gives real Brinell number on production testing.
