The 900-475 is suitable for determining Rockwell hardness of ferrous, non-ferrous metals, and non-metal materials, and is especially suitable for the precise measurement of both flat and curved surfaces.\u003cspan data-state=\"closed\" class=\"inline-flex\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe 900-475 is built around a high accuracy optical grating displacement measuring system with a significant advancement over the encoder-based depth measurement used in earlier load cell Rockwell testers. This system captures indentation depth with greater resolution and linearity, directly translating to more precise and consistent Rockwell hardness results across all test loads. The instrument also incorporates automatic tracking and testing with no test error caused by deformation of the frame and\/or workpiece, further eliminating a common source of measurement variability in traditional designs.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe LED-lighted measuring head moves up and down automatically and applies the preliminary test force without operator input, while the fully automated load cycle handles pre-load, major load, dwell, and unload from a single touch of the start symbol on the display. The 900-475 is the only Phase2+ Rockwell tester to include Bluetooth data interface and an external wireless mini printer in the box which enables cable-free result transmission and on-the-spot hardness test documentation in any environment. Hardness scale conversions are based upon material per ASTM E140-12b (2019), a built-in round part correction factor is included, and precision conforms to ASTM E18, GB\/T 230.2, and ISO 6508.\u003cspan data-state=\"closed\" class=\"inline-flex\"\u003e\u003ca class=\"group\/tag relative h-[18px] rounded-full inline-flex items-center overflow-hidden -translate-y-px cursor-pointer\" href=\"https:\/\/accusizetools.com\/en-us\/products\/phase-ii-new-twin-rockwell-hardness-tester-900-475\" target=\"_blank\"\u003e\u003cspan class=\"relative transition-colors h-full max-w-[180px] overflow-hidden px-1.5 inline-flex items-center font-small rounded-full border-0.5 border-border-300 bg-bg-200 group-hover\/tag:bg-accent-900 group-hover\/tag:border-accent-100\/60\"\u003e\u003cspan class=\"text-nowrap text-text-300 break-all truncate font-normal group-hover\/tag:text-text-200\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Accuracy Optical Grating Displacement Measuring System\u003c\/strong\u003e - Unlike encoder-based depth measurement in conventional digital Rockwell testers, the 900-475 uses an optical grating system for significantly higher resolution indentation depth capture directly improving Rockwell hardness measurement precision and linearity across all scales and test loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic Tracking with Frame Deformation Error Elimination\u003c\/strong\u003e - The measuring head automatically tracks and compensates for workpiece position in real time, eliminating the measurement errors caused by elastic deformation of the tester frame and\/or workpiece that can affect results on conventional motorized designs especially at higher test loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Twin Testing: 30 Rockwell + Superficial Rockwell Scales\u003c\/strong\u003e - Tests all 30 standard Rockwell and Superficial Rockwell hardness scales in one instrument, HRA through HRV and HR15N through HR45Y with automatic conversions to Brinell (HB), Vickers (HV), and all cross-scale outputs per ASTM E140-12b (2019), including built-in round part correction factor for curved surface testing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBluetooth + Wireless Mini Printer Included\u003c\/strong\u003e - The only Phase2+ Rockwell tester with Bluetooth data interface built in, paired with an included external wireless mini printer for cable-free, on-the-spot hardness test result documentation directly at the test station without a PC or tethered cables required for basic reporting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLED-Lighted Auto Measuring Head \u0026amp;
