1.5 Product Features
1) The three parameters of soil moisture content, conductivity and temperature are combined.
2) It can also be used for the integration of water and fertilizer solutions, as well as the
conductivity of other nutrient solutions and substrates.
3) The electrode is made of specially treated alloy material, which can withstand strong external
impact and is not easy to damage.
4) Completely sealed, resistant to acid and alkali corrosion, can be buried in the soil or directly
into the water for long-term dynamic detection.
5) High precision, fast response, good interchangeability, probe plug-in design to ensure
accurate measurement and reliable performance.
2. Instructions
Since the electrode directly measures the conductivity of the soluble salt ions in the soil, the
soil volumetric water content needs to be higher than about 20%, and the soluble ions in the soil
can correctly reflect the conductivity of the soil. In the long-term observation, the measured values
after irrigation or rainfall are closer to the true level. If the quick test is performed, the soil to be
tested can be watered first, and the water is fully infiltrated and measured.
If it is measured on a hard surface, it should be drilled first (the aperture should be smaller than the
diameter of the probe), then inserted into the soil and compacted and then measured; the sensor
should prevent severe vibration and shock, and can not be struck with hard objects. Since the
sensor is packaged in black, the sensor will cause a sharp rise in temperature (up to 50 °C) under
strong sunlight. To prevent excessive temperature from affecting the temperature measurement of
the sensor, please pay attention to shading and protection when using it in the field or in the field. .
2.1 Speed measurement method:
Select the appropriate measurement location, avoid the stone, ensure that the steel needle will not
touch the hard object, throw off the topsoil according to the required measurement depth, keep the
original soil tightness under the ground, hold the sensor vertically into the soil, insert It is not
allowed to sway from side to side. It is recommended to measure the average for multiple
measurements within a small range of one measurement point.
