Model B - 3000(J) : Simplest model of Brinell Hardness tester with mechanical design, loading, unloading manual, best suitable for testingbatch quantities.Model B - 3000(H) : Machine designed with a hydraulic power pack & control circuit for effortless loading unloading operation. A dial gaugein front measures depth of ball penetration. This facilitates production testing within tolerance limits by compression method.Model B - 3000(O) : Basic Machines design & operation similar to B-3000(H). In addition, an 'optical device' with 14x magnification providedin front to project dia of ball impression on glass screen with a micrometer measuring system with 0.01 mm accuracy. The indenter swivels andprojects dia of ball impression immediately after unloading operation which avoids additional time for measurement of ball impression. This givesreal Brinell number on production testing.Brinell Hardness Testers Model B-3000(H), (O) & (J) are precision engineered conforming to IS : 2281 - 1983, BS :240 and 240 and ASTM : E 10, however B-3000 (H), (O), (J) are most suitable for production testing. Thesemachines are designed to measure hardness of casting, forgings, other metals and alloys of all kinds, hard or soft,whether flat, round or irregular in shape.
