1Purpose:

Soil is composed of three phases: solid phase, liquid phase, and gas phase, and their ratio is called the three-phase ratio. This instrument measures this ratio.

IIPrinciple:

The measurement principle is based on Bohr's lawP × V=K. Under air compression conditions, the volume of air is compressed to half, and the air pressure will double. If the pressure of a compressed gas with a known volume can be measured, the unfilled volume of liquid and gas can be calculated. When the temperature rises, the air pressure will increase, so it should be measured in a place where the temperature is relatively constant.
