Further Details:
Fine make hardness testers model IRS, TRS-150_ TRB, TRB-250 and TSM are manually operated_ These models are designed and developed after years of experience in this field. All the models are manufactured under strict quality at all manufacturing stages.
These models are suitable for testing hardness of metals and alloys of all kinds,. hard or soft, whether flat or round etc or of irregular shape. These Testers are simple rn design and easy to operate, still suite sensitive and accurate.
These models strictly conform to iS 3804. BS 891 Part-I &IL ASTM-E-18 for Rockwell test and IS 2281-2005_ BS 240. ASTM-E-10 for Brinell test and IS 5073-1988_ ATM-E-18 for Rockwell Superficial test.
TRS : Automatic weight selection with automatic zero setting dial gauge.
TRS-150 : Automatic weight selection with automatic zero setting dial gauge.
TRS : Automatic weight selection with automatic zero setting dial gauge.
TRB - 250 : Arrangement similar to TRS with two additional weights of 187.5 kgf and 250 kgf for Brinell tests. On this machine small pis having Dia 2 mm can be tested as plunger is guided with a set of six bearings
TSM : This hardness tester is similar to TRB-250 machine in construction and with automatic weight selection. This is useful for carrying Rockwell and Rockwell Superficial Tests. The Rockwell Superficial method is useful for checking hardness of very thin sheets and surface hardness.
