LoadTrac III/FlowTrac III

The LoadTrac III / FlowTrac III system for triaxial testing offers an affordable, high-quality solution for any lab setting. It performs Unconsolidated Undrained (UU), Consolidated Undrained (CU) and Consolidated Drained (CD) testing. Once the sample is placed and test parameters set, the system automates all phases of the test from start to finish - initialization, saturation, consolidation (isotropic, anisotropic, or Ko) and shear. The LoadTrac III and FlowTrac III units take minimal space, require no external connections other than water source, and need minimal maintenance. Additional common test methods can easily be added (1-D Incremental Consolidation, CRS Consolidation, Unconfined Compression), which makes return on investment best on the market.

For users wanting to outfit a production or teaching lab with multiple units having broad test flexibility, using minimal space, and on a limited budget this is a great choice.

Applicable Test Standards
