LoadTrac II

LoadTrac II system for incremental consolidation and swell testing fully automates an entire consolidation test. Constant load and constant volume swell tests can be run automatically. Once a sample is placed in the load frame, the test conditions programmed, and the test started, the LoadTrac II system performs the complete test without intervention by the user. The computer automatically increments to the next stress by using conditions specified by the user. Incremental consolidation test can be completed in 24 to 48 hrs on most materials.
