Product description:
Stem flow is one of the subjects in the study of water balance in forest ecosystems. In hydrology, stemflow is the flow of intercepted water down the trunk or stem of a plant. Stem flow, along with through fall, are responsible for the transferral of precipitation and nutrients from the canopy to the soil. QT-Y/H stem flow collector is used to collect and analyze the stem flow.
QT-Y/H Automatic stem flow collector QT-Y/H Automatic stem flow collector
Principle:
The system is composed of collecting units, a flow sensor and a data logger. It can continuously and automatically record the start time, end time and duration of stem flow, and also stem flow rate. The logged data can be export to excel or text file format to facilitate data processing.
Features：
1. The system is suitable for all kinds of trunks. QT-Y is better for trunk diameter less than 14 cm, QT-H is for more than 14 cm.
2. It is easy to install and battery-powered, no need of external power supply.
3. The system is equipped with a sensor with high resolution of 4.13 ml
4. The data logger can record the air temperature when the stem flow is running.
Technical Parameters:
Recording range: 0 - 66000ml, resolution: 4.13ml;
Storage capability: 16,000 records;
Can set the start time and date;
Download mode: download data through the infrared downloader with USB interface
EEPROM memory, no data loss when power outage;
Fully-sealed data logger can be placed in the flow sensor device;
Internal LED lights indicate operating status;
The battery can last about 1 year.
Event resolution: 1 second;
Temperature measurement range: -20-70℃, temperature accuracy: 0.5℃, resolution: 0.1℃;
Time accuracy: ±1 munities/week;
The system is equipped with a protection case

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

Product description:
The lodging of maize, sorghum and tobacco has caused insufficient illumination, and in turn enormously limited crop yields for a long time. Meanwhile, it has also caused great difficulties in crop mechanized harvesting, thus a lot of grains have been wasted. This instrument can test plant stem strength, and it applies to genetic breeding in agriculture as well.
