HR21M Soil pF Curve Centrifuge
The soil pF curve is determined by the relationship between soil suction, bulk density and weight and water content, so that a high-precision soil moisture characteristic curve pF is obtained.
The soil moisture characteristic curve is usually measured by a pressure membrane (chamber) and a centrifuge. Compared with other methods, the centrifuge method is simple and time-saving, and can measure a wide range of suction force. It is widely used in soil moisture dynamic simulation, meteorological climatology, soil geography, hydrology, and agricultural science and technology.
