Equipment Usage:

• JG-108 is a newly designed automatic full scale digital Rockwell hardness tester.

Features: 

• 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 automatically clamp the workpiece, 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;
• Large LCD display, menu operation, complete function (data processing, hardness conversion between different hardness scales etc.);
• RS232 data interface;
• Equipment with printer
• Optional upper-computer equipment with special software;
• Precision conforms to GB/T 230.2, ISO 6508-2 and ASTM E18
