Used for testing thin and soft material in the Superficial Rockwell hardness scales, this instrument is ruggedly engineered to obtain highly sensitive and accurate readings making it the go-to benchtop solution for thin sheet metals, case-hardened surfaces, lightly coated parts, and other workpieces that demand lighter test forces.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eConforming to ASTM E-18 Superficial Rockwell Hardness standards, the 900-345 offers unmatched repeatability across all Superficial Rockwell hardness scales, including the N series (15N, 30N, 45N) for harder materials tested with a diamond indentor, the T series (15T, 30T, 45T) for softer thin sheet metals tested with a 1\/16\" carbide ball, and the W, X, and Y series for very soft materials tested with larger carbide ball indenters.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eResults are read directly from a precision analog dial gauge, providing immediate battery-free hardness readings cycle after cycle. The 900-345's reduced minor load of just 3 kgf and major loads of 15, 30, and 45 kgf significantly lower than standard Rockwell loads ensure that delicate workpieces are tested accurately without risk of cracking, deforming, or over-penetrating the surface. Lifetime technical support is included with all Phase II hardness testers and NIST\/ASTM certified test blocks, penetrators, and accessory kits are available as options.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePurpose-Built for Thin \u0026amp; Soft Material Testing\u003c\/strong\u003e - Designed specifically for the Superficial Rockwell hardness scales, the 900-345 applies lighter test forces (15, 30, and 45 kgf) that protect thin sheet metals, lightly case-hardened surfaces, coated parts, and soft alloys from over-penetration or surface damage during testing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Superficial Rockwell Scale Coverage - ASTM E-18 Compliant\u003c\/strong\u003e - Supports all Superficial Rockwell scales including HRN (15N, 30N, 45N), HRT (15T, 30T, 45T), HRW (15W, 30W, 45W), HRX, and HRY series, conforming to ASTM E-18 for consistent, traceable results across a wide range of thin and soft materials.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduced Minor Load for Sensitive Applications\u003c\/strong\u003e - A 3 kgf minor (preliminary) load compared to 10 kgf on standard Rockwell testers delivers the gentle pre-load required for accurate Superficial Rockwell testing without disturbing or damaging delicate workpiece surfaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDead Weight Loading with Direct Analog Dial Readout\u003c\/strong\u003e - Dead weight test force application ensures precise, repeatable load delivery on every test cycle, while the direct analog dial gauge provides immediate, battery-free hardness readings with real-time tactile feedback.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenerous Vertical Capacity \u0026amp; Throat Depth\u003c\/strong\u003e - A 6.7\" vertical capacity and 6.6\" throat depth accommodate a
