The auto-turret sensor prevents maloperation of the pressure turret during testing a critical safeguard that protects both the indentor and the objective lens from contact damage caused by inadvertent manual switching under load. The 900-391C and 900-391D models go further, giving operators the ability to control the turret directly through the software, enabling fully PC-driven test sequences from indentation through measurement without touching the instrument.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe 900-391 series includes Auto-Turret, video camera, adapter, USB output cable, and a choice of four variants of measurement software giving users the capabilities of machines that cost thousands more. Conforming to ASTM E-384\/92 Vickers hardness tester standards, the 900-391 series offers unmatched repeatability across a testing range of 1–2967 HV, and can also measure Knoop hardness after installing an optional Knoop indentor. A 5-year warranty and free lifetime technical support are included with every model.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-In Auto-Turret with Maloperation Protection\u003c\/strong\u003e - Every 900-391 model ships with a motorized Auto-Turret integrated into the instrument body, automatically switching between the Vickers indentor and the measurement objective with a built-in sensor that prevents accidental contact between the turret positions during the test cycle, protecting both the diamond indentor and the optical lens.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour Software\/Turret Control Variants in One Series\u003c\/strong\u003e - Choose from four configurations to match your workflow: 900-391A (manual measurement software), 900-391B (auto edge detection software), 900-391C (turret control + manual measurement software), or 900-391D (turret control + auto edge detection software) with all A, B, and C packages upgradeable to the D configuration at any time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePC-Driven Turret Control (900-391C \u0026amp; 900-391D)\u003c\/strong\u003e - The 900-391C and 900-391D enable full software control of the Auto-Turret from a connected PC, allowing operators to execute complete indentation-to-measurement test sequences including turret switching, indentation imaging, diagonal measurement, and hardness calculation without physically operating the instrument.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1–2967 HV Range with 8 Selectable Test Forces\u003c\/strong\u003e - Covers a testing range from 1 HV to 2967 HV across eight test forces (10g, 25g, 50g, 100g, 200g, 300g, 500g, and 1000g) for accurate microhardness testing of thin coatings, case-hardened layers, wires, precision parts, and the hardest carbide and ceramic materials.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVideo Camera, Adapter \u0026amp; Software Included as Standard\u003c\/strong\u003e - All diagonal length measurements, hardness values, data statistics, and hardness conversions are displayed simultaneously on the instrument LCD and on a connected PC, with USB output enabling export to Word or Excel formatted files for documentation and traceability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Vickers \u0026amp; Knoop Testing — ASTM E-384 Compliant\u003c\/strong\u003e - Designed to test in both Vickers (HV) and Knoop (HK) hardness scales with the optional Knoop indentor, the 900-391 conforms to ASTM E-384\/92 and is suited for metallography labs, heat treat QC, failure analysis, weld inspection, coating analysis, and case depth determination across ferrous and non-ferrous metals.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable xmlns=\"http:\/\/www.w3.org\/1999\/xhtml\" cellspacing=\"0\" cellpadding=\"0\" dir=\"ltr\" border=\"1\" data-sheets-root=\"1\" data-sheets-baot=\"1\"\u003e\n\u003ccolgroup\u003e\n\u003ccol width=\"236\"\u003e\n\u003ccol width=\"234\"\u003e\n\u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpecification\u003c\/td\u003e\n\u003ctd\u003eDetails\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel Series\u003c\/td\u003e\n\u003ctd\u003e900-391 (A, B, C, D)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTest Method\u003c\/td\u003e\n\u003ctd\u003eVickers (HV) \/ Knoop (HK, optional indentor)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTurret Type\u003c\/td\u003e\n\u003ctd\u003eBuilt-In Auto-Turret (all variants)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTesting Range\u003c\/td\u003e\n\u003ctd\u003e1 HV – 2,967 HV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTest Forces\u003c\/td\u003e\n\u003ctd\u003e10g, 25g, 50g, 100g, 200g, 300g, 500g, 1,000g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCarriage Control\u003c\/td\u003e\n\u003ctd\u003eAutomatic (load \/ hold \/ unload)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMicroscope Magnification\u003c\/td\u003e\n\u003ctd\u003e100× and 400×\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDwell Time\u003c\/td\u003e\n\u003ctd\u003e5–60 seconds (selectable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin.
