Borehole Pressuremeter Test of Low pressure (for Soil) (Auto LLT2)

The AUTO LLT 2 is a borehole lateral load tester that functions to determine the deformation characteristics of the ground from the relation between pressure inside its sonde and the inflated amount of its rubber tube. A conventional LLT requires gas pressure injection into its tank and the tank makes it difficult to carry the system because the weight of the tank is about 40 kg, while the tank of the AUTO LLT 2 weighs just about 10 kg. In the case of the AUTO LLT 2, the amount of water absorption from its tank and the amount of water supply to its sonde are always the same because of its double acting pump, contributing to its stable and accurate measurements.
