R (D) -150AG Manual digital Rockwell hardness tester
R (D)-150DG High-travel electric Rockwell hardness tester
System features:
- Direct reading of dial hardness number.R (D) -150DG is of automatic loading, load-holding and unloading, which is simple to operate, without any operator errors.R (D)-150AG is of manual loading and unloading (operation without any need of power supply).Stable performance, simple operation, and convenient to use, which is economical and practical.Optimized design of mechanical structure, with linear small arc appearance.Strong structure, with good rigidity, which is reliable, durable, and of high test efficiencyOptional indenters can be selected to extend the hardness scale.Can test some large-scale workpieces.
Application scope
- Rockwell hardness: Used to determine Rockwell hardness of ferrous metals, nonferrous alloys, alloy steels,nonferrous metals, and non-metallic materials; suitable for measurement on Rockwell hardness of materials after heat treatment, such as quenching and tempering;Rockwell superficial hardness: Used to determine Rockwell superficial hardness of ferrous metals, alloy steels, cemented carbides, and after the metal surface treatment (carburizing, nitriding, and electroplating) ;
