Arun Hardness Testers, Model B-3000 (H) & Model 3000 (O) are precision engineered confirming to IS : 22281 – 1968, BS : 240 and ASTM : E 10, however B-3000 (H) & B-3000 (O) are most suitable for production testing. These machines are designed to measure hardness of castings, forgings, other metals and alloys of all kinds, hard or soft, whether flat, round or irregular in shape. Basic machine design & operation similar to B-3000 (H). In addition ‘optical device’ with 14 x magnification provided in front to project dia of ball impression on glass screen with a micrometer measuring system with 0.01mm accuracy. The indentor swivels & projects dia of ball impression immediately after unloading operation which avoids additional time for measurement of ball impression.
