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 hardness 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
