Engineered to ASTM E18 guidelines, the 900-346 replaces traditional dead-weight loading with a closed-loop load cell system that delivers highly accurate, repeatable force application at 15, 30, and 45 kgf major loads eliminating the mechanical variability and maintenance concerns associated with conventional weight-and-lever designs.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eAt the core of the 900-346 is a fully automated motorized test cycle controlled by a micro-computer driven touchscreen. The one-touch testing feature handles the complete load and unload sequence without operator intervention, removing the primary source of human error in superficial Rockwell testing and ensuring consistent indentation depth measurement every time. Results are displayed on a high-definition LCD at 0.01 HR resolution, and the system automatically converts readings to Brinell (HB), Vickers (HV), and standard Rockwell scales, reducing the need for manual conversion charts in production and QC environments.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe 900-346 reads all Superficial Rockwell scales HRN and HRT and accommodates N, T, W, X, and Y indentor combinations across all three load levels, making it a single instrument that covers the full spectrum of superficial hardness testing applications. Programmable dwell times, upper\/lower limit settings, statistical capabilities, and a test counter add the QC documentation tools that production labs and inspection departments require. USB output to PC enables direct data transfer for records, SPC integration, and reporting. For customers requiring documented traceability, the 900-346 is available with ASTM E18-20 certification, and NIST\/ASTM certified test blocks, penetrators, and kits are available as optional accessories.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli class=\"whitespace-normal break-words
