This device measures the actual volume of soil (solid and liquid phase).
Developed focusing on the law that the volume of gas is inversely proportional to its pressure under certain conditions (Boyle’s law). It is an indispensable device for measuring of the three-phase distribution in soil physics.

Renewed the design and function of conventional analog type, its operation is easy to put a sample soil into the device and to press one button. The result is displayed on the screen and the measured data can be saved up to 1000.
