Product description: Equilibrium tensiometer is a new revolutionary soil water potential meter which has patent protection. Soil water potential is measured as potential energy per unit quantity of water under isothermal conditions, its unit is bar (1 bar = 100kPa). In the soil, water potential is a major factor in determining the direction and speed of water flow, which is the only index of the effectiveness of soil moisture to plants. The water potential of different soils can be compared with each other directly. Accurate determination of soil water potential has very important significance for the research on the flow of soil water, drought resistance of plants, automatic control of water-saving irrigation, soil moisture monitoring, etc.
QT-EQ15 Soil water potential meter
Principle
EQ15 equilibrium tensiometer consists of two parts: equilibrium sensor and moisture content sensor. The equilibrium sensor is made of a special material which owns two characteristics: stable relationship between water content and water potential, high water permeability. Good permeability can ensure water potential changes simultaneously with soil water content. Moisture content sensor measure the water content of equilibrium sensor all the time. Because the relationship between water content and water potential is known, soil water potential can be calculated based on soil water content. Moisture content sensor is fixed in the equilibrium sensor, thus the changes of ambient environment (Soil density, gravels, root systems, etc.) around the probe have no effect on the measurement results.
Comparison with traditional soil water potential meter
The current soil water potential meters on the market and their measuring principles have several shortcomings in some aspects, such as measurement accuracy, measurement range and stability in measurement. Apparently those soil water potential meters cannot completely meet users’ requirements. The traditional tensiometer usually has a small mea
