HR-300 & 400 Series
HR Series Rockwell Hardness Testers with Advanced Digital Display and Automation (AI)
Rockwell
Mid-Range HR-320MS, HR-430 Twin Models, and Measurlink® Software Integration for Precision Testing
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.
Features
Features a motor drive that controls the loading sequence to ensure consistent test force application.
Includes a manual handle for straightforward test force and preliminary test force selection.
Equipped with an automatic brake and start system that initiates the major test force cycle once the minor force is reached (HR-430).
Provides a digital display for direct reading of hardness values, reducing human error in result interpretation (HR-430).
Uses a dial-type selection system for quick and easy switching between total test forces (HR-430).
Incorporates an adjustable dwell time feature to meet specific material testing requirements and standards.
