Soil moisture observation instrumentIt is a high-precision soil parameter monitoring device designed based on the frequency domain reflection (FDR) principle, which can measure key indicators such as soil moisture content and temperature in real time and accurately, providing scientific decision support for agriculture, forestry, environmental monitoring, and scientific research fields.

This instrument calculates moisture content by emitting high-frequency electromagnetic waves and detecting changes in soil dielectric constant. Due to the much higher dielectric constant of water compared to other media, changes in soil moisture can directly cause changes in sensor capacitance values, which are then captured and converted into quantifiable moisture data by data collectors. The measurement accuracy can reach ± 2% -3%, and the response time is ≤ 2 seconds, which can capture small changes in soil moisture.

　　Soil moisture observation instrumentBasic operating steps:

1. Power on and settings:

Press the power button on the instrument, wait for the instrument to start and enter the main interface.

Set the measurement mode, unit, time and other parameters of the instrument as needed.

2. Sensor installation and connection:

Insert the soil moisture sensor into the soil at the measurement point, ensuring that the sensor is in close contact with the soil.

Connect signal lines or wireless transmission devices such as Bluetooth between sensors and instruments.

3. Measurement operation:

Start the measurement operation according to the instrument prompt.

Wait for the instrument to display the measurement results and record the data.

If multiple measurements are required, please perform continuous measurements or replace measurement points according to the instrument requirements.

4. Data viewing and export:

View measurement data on the instrument, including real-time data, historical data, or statistical data.

To export data, it can be transferred to a computer or other device through USB interface, Bluetooth, or Wi Fi.

5. Shutdown and storage:

After completing the measurement, press the shutdown button on the instrument to turn it off.

Pull out the sensor, clean it thoroughly, and store it properly.

Store the instrument and its accessories in a dry and well ventilated place.
