AUTOMATIC VANE SHEAR TESTER TPAS-1
The automatic vane shear tester TPAS-1 is a laboratory geotechnical testing equipment used to determine the shear strength of soft soil or sensitive clay. It not only can determine the undrained strength of undisturbed soil taken at different depths, but also can perform tests under different consolidation pressures (this function is optional) and determine soil sensitivity.
