LoadTrac III

The LoadTrac III 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 into the load frame, the test conditions programmed, and the test started, the LoadTrac III system performs the complete test, up to 32 steps without intervention by the user. The computer automatically increments to the next stress by using conditions specified by the user. A test can be completed in 24 to 48 hours on most materials.
