Product Features:
- The loading method is stable and reliable, with a hydraulic loading system that can provide uniform and stable test force.
- Adopting a chain transmission mechanism, which has the advantages of large force transmission and stable operation, and can maintain precise displacement control under high loads.
- On-site testing without sampling. It can test large, assembled, inconveniently moved and non-cuttable workpieces of various materials, sizes and shapes, and can test in any direction, including upper, lower, side, and even inverted testing can get accurate results.
- The instrument uses 1000kg force and 10mm ball. The permanent indentation left after testing can be re-inspected at any time, and the existence of the indentation indicates that the workpiece has been tested for hardness.
- The calibration accuracy of the test force reaches ±1% of the rated load, and the hardness test accuracy is the same as that of the desktop machine.
- Multiple test forces and multiple ball indenters can be used. It has a wide test range, reaching 16~650HBW.
- The test conditions and accuracy comply with the standards: GB/T231.1, ISO6506, ASTM E10
Product Applications:
- Heavy machinery and engineering machinery manufacturing
- Automobile and rail transit industry
- Metallurgy and raw material processing
- Mould and heavy tool manufacturing
