Description

Our Automatic Triaxial Testing System is expertly designed to deliver fully automated total and effective triaxial testing for samples with diameters up to 300 mm and loads reaching up to 250 kN. This static triaxial system efficiently performs a range of tests, including Consolidated Drained (CD), Consolidated Undrained (CU), Unconsolidated Undrained (UU), Stress Path tests, and Slow Cyclic Testing at frequencies up to 0.1 Hz, depending on the amplitude.

Central to the system is the Pro Dual Automatic Pressure Controller, engineered to control and measure both cell and back pressure, as well as volume, for pressures up to 3500 kPa. For projects requiring even higher pressures, we offer advanced systems tailored to your specific needs. Moreover, the static triaxial system is seamlessly integrated with our advanced Clisp Studio software, providing a user-friendly interface for test setup and monitoring via USB or Ethernet connection.

The Clisp Studio software enables real-time display of test results and comprehensive post-test analysis, allowing for the generation and export of detailed reports for further evaluation on a PC. Hence, this combination of precision engineering and advanced software ensures that the Pro Automatic Triaxial Testing System delivers reliable, accurate results for all your geotechnical testing needs.
