Description
Digital Rockwell/ Superficial Rockwell Hardness Tester/Twin Rockwell Superficial Rockwell Hardness Testers
direct ship from PHASEII+ in NJ, USA
Model No. 900-384
Features
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. The result is highly accurate hardness test measurements at all test loads up to 0.5%.
Hardness Tester Features:
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. The result is highly accurate hardness test measurements at all test loads up to 0.5%.
Simple plug – and – play tech allows for much more quick and easy installation than traditional dead weight type machines.
Extended dolphin nose allows vertical hardness test height of 11.8” and throat depth of 8.6”.
Built-in micro-printer.
