Product Description

LCD Display, Test Force Closed-loop Control, Model 300HRSS-150 Automatic Full Scale Rockwell Hardness Tester


* 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 (optional)

* 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.
