QT-WSI soil aggregate analyzer can be used to soil sampling and analysis in laboratory.
The soil aggregate plays an important role in the soil fertility and water movement. A good aggregate structure has generally three characters: diverse pores, certain sizes and stability. The big pores permeate air and water and the small preserve water and fertilizer; the size too large or too small is unfavorable to the formation of appropriate pore proportion; and the certain stability includes water stability, mechanical stability and biological stability.
A good aggregate structure is the basis for soil fertility. The relationship of the aggregate structure and the soil fertility is manifested mainly in the following aspects: 1. Adjust the contradiction between soil moisture and air; 2. Coordinate the contradiction of soil nutrient consumption and accumulation; 3. Stabilize soil temperature and adjust the soil thermal conditions; 4. Improve the soil tilth and facilitate crop roots stretching.
QT-WSI can precipitate soil particles of standard sizes without disturbing the soil aggregate. The meter have four analysis-tubs and five mesh-sieves with standard pores (2.0 mm, 1.0mm, 500μm, 250μm, 106μm). The mesh-sieves move up and down in the analysis-tubs, and five kinds aggregate of particles are precipitated.
Features:
Test four samples at the same time;
Clock control: set test time before operating, and the meter stop on time;
The vibrating frequency is controlled by the transducer, which is digital displaying and adjustable;
The snap-fit connection and special mechanism make it more convenient to install the mesh-sieve components, and ensure the relative locations of four analysis-tubs and mesh-sieves;
Perform stable, operate steady, low noise, long life;
The QT-WSI020 can perform thermostatic test on the samples in the four analysis-tubs at different temperature ranges at the same time. The temperature of each analysis-tub can be controlled independently, and displayed digitally.
