Devices, apparatus, systems and methods for providing a compact, lightweight, handheld pressuremeter controller to perform a soil balloon test with a probe placed into soil, to determine soil strengths and/or stiffnesses/and/or deformations values of the soil. The controller inflates and deflates the balloon through a tubing a quick connect attachment and internal piston-cylinder and tubing components. The controller has a switch, which when activated allows the fully saturated automated device linear or step motor to inject water into the probe while soil resistance pressures and balloon volumes are recorded. Water, or a similar fluid, is injected into the probe until it reaches the prescribed volume. Once that volume is achieved, the motors are controlled to deflate the balloon and the test data is converted from pressure and volume into stress and strain and then to values for soil stiffness and strength.
