• Displacement controlled tests for FRC/Shotcrete characterization (with optional software package 82-SW/DC)

• Suitable for any kind of test from basic failure tests (compression, flexure, splitting, tension) through cyclic tests for elastic modulus and poisson ratio determination up to advanced displacement controlled tests
• Suitable for any type of sample, can be connected up to 4 frames ranging from 15 kN up to 5000 kN in compression and 500 kN in tension
• Suitable for any budget: the machine can be upgraded in step-by-step investments by adding suitable testing frames, accessories and dedicated software packages 
• Suitable for any user: 4 easy-to-use software packages available, each one tailored for a specific test method, guiding the operator through all the test phases
• Test cycle with closed loop PID control automatically performed by pressing the start button via PC
• DC-driven variable speed pump for silent operation, energy saving and highly accurate drop-by-drop oil flow for precise control during complex tests

  PC and software

  Main software MULTITEST allows:

  • Remote control of the whole system and automatic execution of test including: fast approaching, zeroing, test execution, numerical and graphical management of test results, etc.   
  • Active frame selection via software  
  • Printing and saving of customized test reports both for single and batch tests in Excel format    
  • Multi-language selection, customizable with a further local language (only latin characters).
  • Automatic load measurement verification procedure including data acquisition and printing of traceable calibration certificates, when the PC is connected to the digital readout unit mod. 82-P0801/E and the suitable load cells
  • the use of 4 software packages each one tailored for a specific test method
