Overview

The Phase II Model 900-387 Digital Twin Rockwell / Superficial Rockwell Hardness Tester is a digital hardness testing system that performs both Regular Rockwell and Superficial Rockwell hardness testing in a single instrument. Utilizing a closed-loop load cell system rather than traditional dead weights, the tester automatically controls the application of test forces for improved repeatability and ease of operation.

The Model 900-387 features a microcomputer-controlled touch screen, automatic loading and unloading, programmable dwell times, USB output, statistical functions, and automatic hardness conversions. It is designed for quality control laboratories, manufacturing facilities, research laboratories, and production environments requiring accurate Rockwell hardness testing. Phase II states the Model 900-387 is manufactured utilizing the guidelines of ASTM E18.
