Rockwell Hardness Testing Machine

Rockwell Hardness Testing Machine

Features

Couplon make Rockwell Hardness Tester Models SRI- RAS, Couplon - RABI, SRI- RAB250, SRI - TWIN are manually operated. All these models are suitable for testing hardness of metals & alloys of all kinds hard or soft, whether flat, round or irregular in shape. These Testers are simple in design & easy to operate, yet sensitive & accurate. Various models from the wide range are suitable for Engg. Colleges, Laboratories, Toolroom, Inspection Departments, Factories etc. These testers strictly conform to IS : 3804 - 1988, BS : 891 parts 1 & 2, ASTM : E18 for Rockwell Test, IS : 2281 - 1983, BS : 240, ASTM : E10 for Brinell Test & IS : 5073 - 1988, ASTM : E18 for Rockwell Superficial Test.

ROCKWELL SYSTEM

MODEL : Couplon - RAS : Automatic load selection with automatic zero setting dial gauge. Manual Operation.

ROCKWELL / BRINELL COMBINED SYSTEM

MODEL : Couplon - RAB-1 : Automatic load selection with automatic zero setting dial gauge. Facility for Brinell Tests with 187.5 kgf. load with 2.5 mm ball indenter, additional load 250 kgf. with 5 mm ball Indenter for testing hardness of non -ferrous metals. Manual Operation.

MODEL : Couplon - RAB-250 : Similar to 'Couplon - RABI' but bigger capicity Diamond Holder is guided in a set of two bail cage, which enables testing of small pins having dia. less than 6 mm (upto 3mni dia)

ROCKWELL / SUPERFICIAL COMBINED SYSTEM

MODEL : Couplon - TWIN : Manual load selection with automatic zero setting dial gauge. Manual Operation. Diamond Holder is guided in a set of two ball cage, which enables testing of small.
