Phase2+ 900-420/900-440 Superficial Digital Rockwell Hardness Tester SKU:900-420 001" 103-200 ±Phase2+ 900 420 900 440 Superficial Digital Rockwell Hardness Tester The Phase2+ 900 420 and 900 440 are large frame, motorized digital hardness testers built for high throughput laboratory and production QC environments that demand precise, repeatable superficial Rockwell testing on a heavy duty platform. Both models use a closed loop load cell system in place of traditional dead weights, eliminating the mechanical variability, drift, and maintenance
