The sample is auto-lifted to approach the indenter, and hardness testing is completed fully automatically. This delivers higher precision than handle wheel lifting or dead weight type machines, which can be affected by user interaction.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eLike all Phase2+ twin testers, the 900-442 tests both standard Rockwell and Superficial Rockwell hardness in a single instrument, covering the full range of 30 Rockwell scales across both methods and automatically converting results to Brinell (HB), Vickers (HV), and Knoop (HK). The test force is applied via a closed-loop control unit with a load cell, a DC motor, and an electronic measurement and control unit that replace traditional dead weights, resulting in highly accurate hardness measurements at all test loads up to 0.5% accuracy. The 900-442 arrives at a very competitive price point, bringing the latest in Auto-Z Axis technology to buyers at pricing levels never seen before.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFully Automated Z-Axis One-Touch Testing\u003c\/strong\u003e - Press START once and the entire test cycle - sample lifting, pre-load, major load, dwell, unload, and result display completes automatically regardless of sample size, position, or distance from the indenter, eliminating operator interaction and delivering higher precision than manual wheel-lift or dead weight designs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwin Testing: Full Rockwell AND Superficial Rockwell in One Unit\u003c\/strong\u003e - Tests all 30 standard Rockwell and Superficial Rockwell hardness scales in a single instrument including HRA, HRBW, HRC, HRD, HRE, HRF, HR15N, HR30N, HR45N, HR15T, HR30T, HR45T, and more.
