Descriptions: 4 Choice Insect Olfactometer is an instrument applied in studying the behavior of insects with strong ability of activity. Insets communicate with the host plant via odor about the information of spawning, feeding and other activities, so odor is very important for insects. The insects’ olfactory behavior could reveal the chemical relationship between pest and host plant, and could also provide a new way to the prediction, monitoring and prevention of pests.

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.
QT-IN12-W Double Ring Infiltrometer
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
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
