Calibration: Gently wipe to remove oxides from metal electrodes.
Purpose: To measure the PH value and water content of different soils.
It is suitable for measuring surface acidity and deep soil acidity.

Usage method:
1. If the soil at the measuring point is too dry or too much fertilizer to measure the acidity and alkalinity of the soil, water should be sprinkled on the location of the measuring point and then determined after 28 minutes.
2. Before using, the abrasive cloth should be used first, and the metal absorption plate should be completely wiped and cleaned in order to avoid affecting the measured value. If the new product is not used, there is protective oil on the surface of the metal plate, it must be inserted into the soil several times, grinding the protective oil layer before using it.
3. The density, humidity and excessive fertility of the soil may affect the measured value, so it must be measured several times at different locations in order to obtain the average value.
4. The acid-base value of the detector is stable after 10 minutes. Press the white button on the side and the humidity will be displayed immediately.
Be careful:
When the probe is used for the first time, it is inserted several times in the soil to remove the oil and impurities on it. When measuring the soil pH and humidity, the probe is inserted into the soil as deep as possible. After about 10 minutes, the pH value is read and the water will be displayed by pressing the white button next to it.
When using, pay attention to inserting the electrode, do not touch the stone, do not exert too much force, otherwise it is easy to damage the electrode; do not put the instrument and magnetic materials together, do not keep in the soil for more than an hour. Wash the electrode after use.
