Geosynthetics direct shear friction tester

1. This machine is versatile and can perform both direct shear friction tests and tensile friction tests on geotechnical materials, making it the first of its kind in China.

2. Adopting a dual display screen system for normal force and shear force, equipped with high-precision sensors that can directly display force values and displacement data;

3. On the testing program, the shear stress is directly converted to kilopascals without the need for manual conversion. The normal force is applied by pneumatic loading, and the air pressure system is dynamically adjusted to maintain a constant pressure state at all times.

4. Adopting a fully stainless steel workbench, it is easy to clean and organize, effectively preventing soil particles from entering the interior of the instrument.

5. Configure JIGAOTEST expert testing software with software copyright certificate, certificate number: 2018SR124282

6. The software must have a software testing report certificate issued by a national inspection and testing agency, and the "CMA" logo must be reflected on the testing report.7. The dynamic data collection frequency is over 3000 times per second, which objectively reflects the mechanical properties of the material;

8. Philips RM32 industrial grade microcontroller control, 16 bit A/D converter, strong anti-interference performance, fast data transmission;

9. Computer processing of reports, graphics, screen displays, or printed outputs; Support remote online software upgrade

10. Operating software system function: The instrument can be connected to a PC to record the entire test process, display real-time curve graphs, shear force, and tensile force, and calculate test dates, shear stress, horizontal displacement, and other data and curve graphs. It can analyze in detail the data changes during each stage of the experimental process, and various statistical indicators such as CV values can be saved and exported to an Excel table at will.
