The Rockwell Hardness Tester Series delivers fast, non-destructive hardness screening for heat-treated parts, finished components, and incoming material inspection, with analog, digital, and automatic models covering HRA, HRB, HRC, and superficial scales for materials from soft aluminum to hardened steel up to 70 HRC. Designed with cast iron frames and precision ball screw loading mechanisms, the rockwell hardness testing machine maintains accuracy drift below 0.5 HRC over extended use, fully complying with ASTM E18 and GB/T 230.1 standards. Models feature touchscreen interfaces, data export via USB/RS232, and optional motorized test cycles for high-throughput environments. Whether for workshop floor screening or laboratory-grade quality assurance, the Rockwell Hardness Tester Series delivers reliable, repeatable results with minimal training – ideal for automotive, aerospace, and general manufacturing quality control applications.
