Hardness Tester

Rockwell, Rockwell cum Brinell, Rockwell cum Rockwell Superficial

Hardness Testers 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, 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.

These models strictly conforms to IS: 1586-2000, BS: 891 part 1 & 2 for Rockwell & Rockwell superficial test. IS: 2281-1983, ASTM-E-10 for brinell test.

Rockwell System

Automatic weight selection with automatic zero setting dial gauge.
Automatic weight selection with automatic zero setting dial gauge with more testing height and throat.

Rockwell cum Brinell Combined System

Automatic weight selection with automatic zero setting dial gauge.
Arrangement similar to RS with two additional weights of 185.5 kgf and 250 kgf for brinell tests. On this machine
small pin having Dia 2 mm can be tested as plunger is guided with a set of six bearings.

Rockwell cum Rockwell Superficial Combined

This hardness tester is similar above 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.

Motorized Hardness Tester models are also available in the above models.

Application and removal of major load is motorized. Motorized models have semi automatic operations for products testing. Drive motor-single phase, 230-V, 50 cycles AC.
