Test force closed-loop control, tracking measurement, automatic clamping during operation
| Main features | Application scope |
| lExperimental force closed-loop control | Determination of Rockwell and surface Rockwell hardness of ferrous metals, alloy steels, hard alloys, and metal surfaces after treatment (carburizing, nitriding, electroplating) |
| Automatic tracking measurement, measurement errors introduced by deformation of inorganic frame and working deformation | |
| Measuring head can automatically move up and down, clamp the workpiece automatically, and there is no need to manually apply initial testing force | Widely applicable, especially suitable for precise measurement of parallel planes and irregular workpieces |
| High precision grating displacement measurement system | |
| Large workbench, capable of measuring irregular and heavy parts | |
| First measurement is considered effective measurement | |
| LCD display screen, menu operation, fully functional (data processing, hardness conversion, etc.) | |
| RS232 data interface | |
| Optional upper computer with dedicated software | |
| Accuracy meets GB/T230.2, ISO 6508-2 and ASTM E18 |
