Product description: QT-AT 502 Chlorophyll Meter can measure chlorophyll content of plants. Chlorophyll content is an important index of plant growth. This instrument is powerful, portable, and easy to use. It does no harm to plants. Users just need to put a leaf tissue larger than 3mm in the aperture, and then press the button to get the chlorophyll content reading.
QT-AT 502 Portable Chlorophyll Meter
Features:
· The measurements can be designated to up to 500 plant names;
· With a
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: Surface runoff is the flow of water that occurs when excess water from rain, meltwater, or other sources flows over the earth's surface. This might occur because soil is saturated to full capacity, or because rain arrives more quickly than soil can absorb it. Surface runoff is a major component of the water cycle. It is the primary agent in soil erosion by water. QT series tipping bucket flowmeter can be used to monitor no-pressure, low-head, and small discharge flow of
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.
