The HA-ZLZ-3000 Plant Moisture Condition Measuring Instrument is a specialized tool designed to measure plant water potential (Ψ) and its individual components, while also enabling the extraction of xylem sap for further chemical analysis. This device plays a crucial role in understanding the water dynamics within plants and their interaction with the surrounding environment. It is widely used in fields such as plant physiology, ecology, agronomy, forestry, and pasture management. As an essential instrument for both educational instruction and scientific research, it supports efforts in optimizing water usage and developing drought-resistant crop and forest species. The instrument is user-friendly, efficient, and suitable for use in both laboratory and field settings.
The specifications of the HA-ZLZ-3000 include a measurement range of 0 to 10.00 MPa, with a digital display for easy reading. The accuracy of the readings is ±0.01 MPa, ensuring reliable results. The instrument has dimensions of 550 mm × 280 mm × 350 mm and weighs 9 kg, making it portable and convenient for various applications.
The working principle of the instrument is based on the soil-plant-atmosphere continuum. In this system, roots absorb water from the soil, while leaves transpire water into the atmosphere. A water potential gradient exists along the root-stem-leaf axis, which creates a negative pressure that pulls water upward through the xylem. When a branch or leaf is cut, the tensioned water column breaks, and the water retracts toward the cut surface. By placing the cut sample into the instrument's pressure chamber and applying controlled pressure, the internal tension is restored, and the water column is pushed back to the cut surface. The pressure required to restore the water column represents the plant’s water potential.
The HA-ZLZ-3000 comes with a variety of accessories, including O-shaped rubber gaskets with different inner and outer diameters, slits, and hole sizes, as well as stainless steel copper gaskets and a high-pressure metal hose. Additional components include a transition joint for gas cylinders, a 3x magnifying glass, and other necessary tools for accurate measurements. These accessories ensure compatibility with a wide range of plant samples and experimental setups.
