DIIGIITAL ROCKWELL HARDNESS TESTER D G TAL ROCKWELL HARDNESS TESTER MODEL: HRS-150 MODEL: HRS-150 Application Rockwell hardness tester is a simple instrument to test the Rockwell hardness value of hard metals, carburized steels, quenched steels, hard cast irons, mild steels, Al-alloys,Cu-alloys and melleable irons according to Rockwell Principle conforms to ISO 6508 and ASTM E18. It measures the depth difference between the primary and testing load and convert the depth difference to the hardness value. HRS-150 is Rockwell test with scales A-B-C(60/100/150kgf) with digital indicator and motor control loading. Hardness value can convert to HV, HB.
