Qt-Wm Series Handheld Weather Station

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.

Http://www.Channeleco.Com/en/item/show.Asp?m=1&d=1195 Product description: a reasonable assessment of water balance and evapotranspiration is an important part of hydrological cycle; a lysimeter is a useful tool to evaluate the use of water in the soil, water storage and transfer in the same location. Qt-3051 series lysimeter can apply to laboratory for the study on parameters relevant to water balance. To make calculation easy, the height of column barrel of this system is designed to 300 mm, 600 mm, 1200 mm respectively, other height can be customized. The system uses state-of-the-art high-resolution weighing system, high-precision soil moisture and water potential sensor to ensure the accurate measurement of the entire system. Applications The lysimeter system can be used in many area, such as water characteristic curve, ecological restoration, small-scale simulation experiment, fluidity of soil water, soil mass transfer, soil absorption and buffering, water balance analysis, leachate analysis, groundwater recharge analysis, mass migration, material transformation research, farming method research, climate research, energy balance studies, correction of simulation experiment, water flux studies, simulation studies on groundwater recharge, determination of the leachate and so on. Measurement parameters Soil column weight Soil water potential Soil moisture Soil temperature Data acquisition Basic input: 8 differential analog channels Channel extension: am16/32 channel expansion module, 32 differential analog channel Storage capacity: 4m memory card

Product description: QT-SM101 is based on TDR (Time domain Reflectometry) technology, it can be used to rapidly measure the moisture of various types of soils. By measuring the dielectric constant of soil or other media, the meter can calculate soil water content, because soil water content is closely related to the dielectric constant. Soil temperature is measured via high-precision thermistor. Soil moisture and temperature data can be transmitted to a handheld Android terminal by WIFI. Feature GPS coordination can be recorded Record data automatically or manually Wireless data transmission via Wi-Fi Recognize sensors by two-dimensional code Automatically recognize connected sensors Terminal memory card is up to 32G Display real-time data and curve of recorded data Export data to Excel for analysis
