Rockwell/Superficial/Brinell

The mid-range HR-320MS is selectable for both Rockwell and Rockwell/ Superficial scales. The HR-320MS features a high contrast LCD digital display, conversions for all common scales, and a motor driven loading sequence.

The HR-430 Series is available in Rockwell-only or Rockwell/Superficial Twin Tester models. HR-430 models feature an automatic brake-and-start feature to prevent overloads during the minor load cycle and to initiate testing when the proper load is achieved. HR-430 testers also include the convenient dial-a-weight major load selection system. 

All HR Series hardness testers can perform Brinell hardness tests when equipped with available optional accessories: a Brinell indenter, weight set and measurement microscope.  

HR Series Rockwell hardness testing machines support Measurlink®, Mitutoyo proprietary statistical processing and process control software. Measurlink® performs measurement data analysis and provides real-time display of measurement results for SPC Software and other management routines. The program also provides archiving and can be linked to a higher-level network environment for enterprise-wide functionality.

The closed loop test force control on the HR-530 Rockwell and Brinell Hardness Tester feature a unique electronic control design capable of Rockwell, Rockwell Superficial, Rockwell testing of plastics (A & B) and Light Force Brinell hardness testing. The HR- 530 is capable of testing the inside wall hardness of rings without cutting the ring into pieces. An easy-to-use brake-start system automatically begins testing when initial force is reached. 

• The curved surface correction function enables curved surfaces, such as round bars and spheres, to be tested for hardness as easily as flat surfaces
• Color touch screen control panel displays statistics and graphs; up to five display formats show needed information
• Nose-type indenter enables measurement of a specimen's flat top surface as well as inside surface of cylindrical specimen
• The HR-530 is available in 9.8" (250mm) or 15.S" (395mm) height capacity models
• Complete with a combination diamond indenter, a 1/16" carbide ball indenter, one flat and one V anvil, 2 HRC, 1 HRBW, 1 HR30TW and 1 HR30N test block
• Hardness testing of plastics according to ASTM D785 (Procedure A and B) and 1SO2039-2 are also possible

The HR-600 Series combines the functionality of several previous models: Rockwell hardness testing, Brinell hardness testing, Brinell and Vickers depth measurement hardness testing, and hardness testing of plastic materials. Supporting all test types in a single machine, this new series expands the range of available measurements.

With its high-resolution scale load cell developed uniquely by Mitutoyo that allows for high-precision test load feedback control and state-of-the-art design that delivers both aesthetics and usability on the ground, the new HR-600 Series enables hardness testing that defies conventional thinking.

New design with one functional beauty, with a table for mounting workpieces and head with vertical mobility, the HR-600 Series is built for operability and usability. Its new design is highly focused on end-user usability, and the entire product structure has been inventively modified for functional beauty- a true embodiment of Mitutoyo's pioneering spirit.
