application

Balanced soil moisture tensiometer(EquilibriumTensiometer)It is a new revolutionary instrument for measuring soil water potential. Water potential is the energy required to extract a unit of water from soil under isothermal conditions, measured in bars(bar，1 bar=100kPa)

In soil, water potential is the main factor determining the direction and velocity of water flow, and it is the only indicator for determining the effectiveness of soil moisture on plants. The water potential of different soils can be directly compared with each other.

Accurately measuring water potential is of great significance in studying soil moisture flow, plant drought resistance physiology, automatic control of water-saving irrigation, soil moisture monitoring, and other aspects. (Origin: Germany)Product principle

EQ15

A balanced tension meter consists of two parts: a balance sensor and a moisture content measuring device. The balance sensor is composed of a special material, This material has two characteristics: a stable relationship between water content and water potential, and high permeability. Good permeability ensures that its water potential changes synchronously with the measured soil. The moisture content measuring device constantly measures the moisture content in the balance sensor. As the relationship between moisture content and water potential is known, the measured moisture content is equivalent to the measured soil water potential. The moisture content measuring device is fixed inside the balance sensor, and the environmental conditions around the probe remain stable and unchanged, thus avoiding the common effects of soil density, stones, and roots when measuring moisture content and ensuring the accuracy of water potential measurement.
