Rockwell/Superficial Rockwell Hardness Testers/Hardness Testers/Automatic Hardness Testers

New! Digital Rockwell/Superficial Rockwell Hard Tester

 

Model No. 900-475 is a newly designed fully automated digital Rockwell hardness tester.

 

Applications:

  • Suitable to determine the Rockwell hardness of ferrous, non-ferrous metals, and non-metal materials.
  • Quality control for metal heat treatment, material inspection, welding evaluations, production
    evaluations involving alloys, Grade verification for hard plastics, and failure analysis.
  • Especially suitable for the precise measurement of flat surfaces as well as a curved surface.

 

Features:

  • Test force closed-loop control;
  • Automatic tracking and testing, no test error caused by deformation of frame and/or workpiece.
  • LED lighted measuring head can move up and down and automatically applies preliminary test force
  • Conversions based upon material per ASTM E140-12b (2019)
  • Round part correction factor
  • High accuracy optical grating displacement measuring system
  • Large test table, which is suitable for testing of abnormal shapes and heavy workpieces.
  • Large LCD display, menu operation, complete functions (data processing, hardness conversion between different hardnes scales etc.).
  • Bluetooth data interface
  • Includes external wireless mini printer
  • 36 • Precision conforms to guidelines set by ASTM E18, GB/T 230.2, and ISO 65
