300HRSS-150 Automatic Full Scale Rockwell Hardness Tester
 

300HRSS-150 Automatic Full Scale Rockwell Hardness Tester is suitable to determine the Rockwell & Superficial Rockwell hardness of ferrous metals, alloy steel and hard alloy, as well as treated layers of metal surface, such as carburized layer, nitrided layer and electroplated coating, etc. It's especially suitable to determine heterotypic workpiece.

Feature & Use

Test force closed-loop control

Automatic tracking and testing, no test error caused by deformation of frame and workpiece

Measuring head can move upwards or downwards and clamp the workpiece automatically, no need to apply preliminary test force by hand

High accuracy optical grating displacement measuring system

Large test table, which is suitable for testing of abnormal shape and heavy workpieces

The first test is effective 

Large LCD display, menu operation, complete functions (data processing, hardness conversion between different hardness scales)

RS232 data interface

Upper-computer is optional (equipped with special software)

Precision conforms to GB/T 230.2, ISO 6508-2 and ASTM E18

It's suitable to determine the Rockwell & Superficial Rockwell hardness of ferrous metals, alloy steel and hard alloy, as well as treated layers of metal surface, such as carburized layer, nitrided layer and electroplated coating, etc. It's especially suitable to determine heterotypic workpiece.
