Graphical instrument overview and data zoom functions
Software-controlled measurement protocols
 
Description
This instrument measures how prone the soil is to slip under both vertical and horizontal stress. This is very useful in research prior to the construction of dikes, railways, large and heavy buildings or other engineering applications that put a lot of stress on the soil. 
During shearing at a constant shear velocity and under either consolidated drained (CD), unconsolidated, undrained (UU) or unconsolidated drained (UD) conditions, the matric potential and shear forces at a given vertical stress are measured simultaneously.
The apparatus operates under computer control, using multifunctional software for executing measurement protocols and visualised data presentation. Samples are taken in a soil sample ring sized Ø 103 x 100 mm, height 30 mm, contents 235 cc.
