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 surface or underground runoff.

Application: QT-SZZ series Increment Borer is a specialized tool to determine the age and the growth increment of a tree by exacting a section of wood tissue from a living tree with relatively minor injury to the plant. By examining the core sample, the user can reveal several indices of a tree, such as growth rate, age, compactness, even including pollution status of the environment where the tree lives and nutrient transport in the tree.
