The Demo kit is used to demonstrate the execution of DMT tests without inserting the blade in the ground. It is composed of a metallic base with two supports for holding vertically a DMT blade (not included) and a syringe for expanding the DMT membrane, with a built-in electric circuit that activates the acoustic signal when the membrane is in the A and B position. The kit also contains a clamp for closing the membrane, in order to simulate the horizontal pressure of the soil.
