(Rockwell, Rockwell Cum Brinell, Rockwell Cum Rockwell Superficial)
Meta-Test make hardness testers model MRS, MRS-150, MRB, MRB-250 and MSM Are manually operated. These models are designed and developed after years of experience in this field. All the models are manufactured under strict quality control at all manufacturing stages.
These models are suitable for testing hardness of metals and alloys of all kinds, hard or soft, metals and alloys of all kinds, hard or soft, whether flat or round etc. or of irregular shape. These testers are simple in design and easy to operate, still yet quite sensitive and accurate.
Various models from the wide range are available for institutes, Quality control laboratories, Tool-Rooms, Heat Treatment Dept. R& D Laboratories etc.
These models strictly conform to IS: 1586-2000, BS: 891 Part 1 & 2 for Rockwell & Rockwell Superficial Test. IS: 2281-2005, ASTM-E-10 for Brinell Test.
Rockwell hardness tester
MRS: Automatic weight selection with automatic zero setting dial gauge.
MRS-150: Automatic weight selection with automatic zero setting dial gauge with more
testing height and throat.
Rockwell cum brinell hardness tester
MRB: Automatic weight selection with automatic zero setting dial gauge.
MRB-250: Arrangement similar to MRS with two additional weights of 187.5 kgf and
250 kgf for Brinell tests. On this machine small pin having Dia 2mm can be
tested as plunger is guided with a set of six bearings.
Rockwell cum rockwell superficial hardness tester
MSM: This hardness tester is similar to MRB-250 machine in construction and with automatic weight selection. This is useful for carrying Rockwell and Rockwell Superficial Tests. The Rockwell Superficial method of useful for checking hardness of very thin sheets and surface hardness.
