Product description: QT-ML3 portable soil moisture/temperature meter can be used for the measurement of moisture of various types of soil and media, and it can be used as a basic tool for on-site observation or mobile measurement.
QT-ML3 Portable soil moisture/temperature meter
Principle
Using FDR (frequency domain reflectometry) principle, the sensor emits electromagnetic wave with a certain frequency, the waves transmit along the probe till they reach the bottom of the probe and return to the sensor, the output voltage is recorded. Because the dielectric constant of the soil usually depends on the soil moisture, the soil water content can be calculated according to the relationship between the output voltage and soil moisture.

Product description: The QT-SM01 is a soil moisture meter, consisting of a soil moisture sensor and a portable data logger. It can apply to agriculture, forestry, environmental protection, water conservancy, meteorology and other sectors for soil moisture monitoring, irrigation, greenhouse control and precision agriculture. The meter can be used to rapidly measure the moisture of various types of soils at upper and lower layer. It is able to meet the requirements of soil moisture monitoring,
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
