Overview
The Phase II Model 900-415 Digital Rockwell Hardness Tester is a bench-top hardness testing system designed for Regular Rockwell hardness testing using a closed-loop electronic load cell for precise force control. Unlike traditional dead-weight testers, the Model 900-415 automatically applies and controls the test force through a motorized system, improving repeatability while reducing operator influence.
The tester features a microcomputer-controlled touch screen, automatic loading and unloading, programmable dwell times, automatic hardness conversions, statistical analysis, USB output, and tolerance settings. The Model 900-415 is intended for quality control laboratories, production facilities, machine shops, heat-treating operations, and inspection departments. Phase II states the tester is manufactured utilizing the guidelines of ASTM E18.
Applications
The Model 900-415 is well suited for testing:
- Heat-treated steel
