QYH-96 Plastic Ball Indentation Hardness Tester

configuration

1. Petrochemical specific ball indentation can be applied continuously for 24 hours, and is equipped with a diameter of 1.8 mm indenter to meet the requirements of SY/T 0413-2002 "Polyethylene Anti corrosion Technical Standard for Buried Steel Pipelines" (Appendix F Indentation Hardness Determination Method).
2. Measure the ability of polymer materials to resist being pressed in by another rigid object that is considered to not undergo elastic deformation. It adopts an X-input electronic servo system, which can automatically load, hold, and detect digital positions.
3. The experimental data can be printed.
4. This machine is a new type of intelligent instrument Color LCD Chinese display is currently one of the W-Y type ball indentation hardness testers in China that can perform two hardness tests simultaneously. It is also the instrument with better performance and price ratio among similar products.

Note: According to user requirements, a Chinese or English operating interface can be provided

1. One set of experimental host
2. One 1.8mm indenter
3. One 5mm indenter
4. One 10mm indenter
5. One micro printer (panel type)
6. One set of specialized tools
7. One user manual
