Product description: Double ring infiltrometer is a simple device used to measure the rate of water infiltration into soil. Water infiltration rate is the water flows into a unit cross section of soil per unit time. It can be calculated by the measuring results and Darcy's law.
The standard device includes several sets of stainless steel rings with different diameter, which can deal with several measurements at the same time to get accurate and reliable results. When vertical water flows to the edge, the outer ring of the infiltrometer will play a role in isolation. The water in the inner ring flows vertically, thus the measurement only occurs in the inner ring. Press these two rings into the soil a few centimeters deep by shock absorbing hammer. Because the inner and outer rings are filled with water, the water actually infiltrates vertically from the inner ring into the soil. To achieve a good result, the following factors that may affect the measurement should be taken into account: surface vegetation, soil density, soil temperature and soil layers. The best measurement results are derived from on-site water holding capacity.
Application:
Geology, civil engineering, hydrology, forestry, environmental testing, hydrogeology, runoff, swamp protection, permeability testing, construction project etc.
Measuring standard:
The soil with infiltration rate within 1X10-2 cm/s or sandy soil with higher infiltration rates.

· Made of durable stainless steel.
· Cross stainless steel tubes in the center to keep steady.
· Easy to press into soils
· Easy to operate with perpendicular steel handles

Product description: Plant root length and root surface area are important indexes to measure crop growth status because they are closely related to the intensity of crop photosynthesis and absorption of water and nutrients. The traditional manual method of cleaning and measurement of plant root systems requires a lot of time and labor work, and it is also prone to errors, which could seriously affect experimental process and accuracy. Root washing is a very important preliminary work for measurements of root systems, however, heavy loss of fine roots would seriously affect the reliability of measurements. QT-RW root system analyzer helps gently separate root systems from soil by swirling water and then collect all the roots in a 500-micron mesh filter. QT-RW root analyze system follows the design of the Australian Commonwealth Scientific and Industrial Research Organization (CSIRO) and it can well keep the integrity of fine roots, which can ensure the reliability of follow-up measurements by software.
