- Automatic weight selection with automatic zero setting dial gauge.
- Rockwell test minor load is 10 kgf & major loads are 60,100,150 kgf. Brinell test for Model : MRB major load is 187.5 & for Model :MRB-250 are 187.5, 250 kgf.
- Rockwell hardness scales such as HRA, HRB, HRC, etc. Brinell hardness scale such as HB is obtained by using different types of indentors( Diamond / Ball ).
- For Model : ASI-RHTB, Test height x Throat is-215 x 132 mm. For Model : ASI-RHTB2,Test height x Throat is-295 x 148 mm.
- Motorized versions are also available.
- Machines strictly conforms to IS:1586- 2000 for Rockwell test, IS:2281,BS:240, ASTM-E-10 for Brinell test.

Versatility in Hardness TestingThis tester facilitates comprehensive metal and alloy evaluation by combining both Rockwell and Brinell testing methods. The use of multiple indenter types and adjustable load settings enables accurate analysis of varying material hardness, ensuring that both softer and harder specimens can be tested efficiently within standardized ranges.
Precision and Reliable ResultsEngineered for accuracy, the device conforms to IS: 2281, IS: 1586, BS: 240, and ASTM E-10/E-18 standards. The analog dial indicator provides immediate manual readings, with a resolution of 0.5 Rockwell units. Its high-quality cast iron construction and precision loading mechanism reduce errors and support consistent, repeatable results.
Ease of Use and Safety FeaturesDesigned for straightforward, single-operator control, it employs a manual lever-operated loading and unloading process. Overload protection safeguards both user and equipment, while ergonomic features like flat and V anvils simplify specimen placement. The included wooden case and dust cover enhance storage and durability in challenging lab settings.
FAQ's of Rockwell Cum Brinell Hardness Tester:
Q: How do I operate the Rockwell Cum Brinell Hardness Tester?
A: Operation is manual, using the lever to load and unload specimens. Position your sample securely on the appropriate anvil, select the desired indenter and load, and follow the dial indicator to obtain immediate hardness readings.
Q: What types of materials can I test with this equipment?
A: You can evaluate the hardness of metals and alloys, both flat specimens up to 150 mm in height and round specimens with diameters from 10-60 mm, across Rockwell B, Rockwell C, and Brinell scales.
Q: When should I choose between the diamond cone, steel ball, and tungsten carbide ball indenters?
A: The diamond cone is ideal for harder materials (Rockwell C). The 1/16" ball-steel or tungsten carbide-should be used for softer to medium-hard specimens, following ASTM and IS standards for specific scale requirements.
Q: Where should this hardness tester be installed for optimal performance?
A: It is designed for tabletop mounting in controlled lab environments, such as metallurgical laboratories or quality control departments. Maintain conditions between 10C to 40C with humidity less than 80% RH.
Q: What is the process for switching between Rockwell and Brinell tests?
A: Switching is manual: install the appropriate indenter and select the corresponding test block and load. The conversion table provided aids in interpreting results across scales, ensuring accurate testing for both methods.
Q: How does the device ensure operator and equipment safety?
A: Safety is built in through overload protection, a sturdy cast iron body, a baked enamel finish for corrosion resistance, and secure accessories such as dust cover and wooden packaging for safe transport and storage.
Q: What are the benefits of using this hardness tester in your laboratory?
A: This tester provides versatility for multiple hardness scales, accuracy certified to key standards, rapid manual results, robust construction for longevity, and an ergonomic design enabling one-person operation-all essential for efficient material quality assessment.
