Phase2+ 900-442 Fully Automated Z-Axis Twin Rockwell Hardness Tester
The Phase2+ 900-442 is the newest addition to Phase2+'s Twin Rockwell/Superficial Rockwell hardness tester lineup, combining the classic cast body design trusted in labs and production environments worldwide with a fully automated Z-axis system that removes the last remaining manual step from the Rockwell testing cycle.
With Auto-Z Axis technology, operators simply press the START key once and the entire test process completes automatically regardless of the size or position of the sample, or the distance between the indenter and the sample surface. The sample is auto-lifted to approach the indenter, and hardness testing is completed fully automatically. This delivers higher precision than handle wheel lifting or dead weight type machines, which can be affected by user interaction.
Like all Phase2+ twin testers, the 900-442 tests both standard Rockwell and Superficial Rockwell hardness in a single instrument, covering the full range of 30 Rockwell scales across both methods and automatically converting results to Brinell (HB), Vickers (HV), and Knoop (HK). The test force is applied via a closed-loop control unit with a load cell, a DC motor, and an electronic measurement and control unit that replace traditional dead weights, resulting in highly accurate hardness measurements at all test loads up to 0.5% accuracy. The 900-442 arrives at a very competitive price point, bringing the latest in Auto-Z Axis technology to buyers at pricing levels never seen before.
Key Features
-
Fully Automated Z-Axis One-Touch Testing - Press START once and the entire test cycle - sample lifting, pre-load, major load, dwell, unload, and result display completes automatically regardless of sample size, position, or distance from the indenter, eliminating operator interaction and delivering higher precision than manual wheel-lift or dead weight designs.
-
Twin Testing: Full Rockwell AND Superficial Rockwell in One Unit - Tests all 30 standard Rockwell and Superficial Rockwell hardness scales in a single instrument including HRA, HRBW, HRC, HRD, HRE, HRF, HR15N, HR30N, HR45N, HR15T, HR30T, HR45T, and more. Eliminating the need for two separate testers and reducing bench space, capital cost, and calibration burden.
-
Closed-Loop Load Cell for ±0.5% Force Accuracy - Direct load cell force application via a closed-loop control unit and DC motor replaces traditional dead weights, eliminating mechanical friction, vibration sensitivity, and load variability for fast, repeatable, and accurate hardness measurements across all six available major loads.
-
Classic Cast Body Design for Maximum Rigidity - Built on Phase2+'s proven classic cast body frame, the 900-442 delivers the structural rigidity, vibration damping, and long-term dimensional stability required for high-precision Rockwell hardness testing in demanding production and laboratory environments.
-
Auto Multi-Scale Conversion with Touch Screen Interface - A microcomputer-controlled touch screen displays results and automatically converts hardness readings to Brinell (HB), Vickers (HV), Knoop (HK), and all Rockwell and Superficial Rockwell scales, with programmable dwell times, scale conversions, statistical functions, upper/lower limit settings, and USB data output.
-
Competitive Price Point - Advanced Automation, Accessible Cost - Brings fully automated Z-axis twin Rockwell/Superficial Rockwell hardness testing technology to market at pricing levels not previously available in this category, making high-throughput automated hardness testing accessible for a wider range of shops, labs, and QC environments.
