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: 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
I HAVE A VERY GOOD CONDITION CLEANED AND TESTED ZENITH 6,500 BTU 120 VOLT 6.2 AMPS DIGITAL WINDOW AIR CONDITIONER WITH ADJUSTABLE SIDES. COME OVER AND FEEL IT COOL BEFORE YOU BUY IT.
We have 2 LG portable air conditioners for sale, both with remotes, tubes for windows, and window inserts. Great condition, cools down a room nicely. Two different models, but pretty much the same.
