Soil PH sensor indispensable for planting novices
Soil pH will not only affect the solubility of various elements in the soil, but also affect microorganisms. Once the soil is acidified (the pH value is lowered), filamentous fungi will grow preferentially, and there are many filamentous fungi, such as the crop pathogens of Fusarium, so special attention must be paid to soil diseases.
Different crops require different pH values. Long-term use of chemical fertilizers without organic fertilizers leads to a decrease in the pH value of some soils, resulting in a decline in soil production potential and soil environmental quality. In order to ensure the healthy growth of plants, scientific and technological means The measurement of soil PH value is conducive to timely understanding of the physical condition of the soil, and plays an important role in rational fertilization, soil improvement, and strengthening of soil environmental management.
RY-CXW300 soil pH sensor solves the shortcomings of traditional soil pH, such as requiring professional display instrument, cumbersome calibration, difficult integration, high power consumption, expensive price, and difficult carrying.
1. When the sensor leaves the factory, there is a transparent protective cover at the probe position, and the built-in protective liquid protects the probe. When using, please remove the protective cover at first, fix the filter tank and the sensor, then use the attached cable tie to wrap the filter in the filter tank. To prevent direct contact between the soil and the probe and damage the probe. In actual use, please ensure that the filter trough and the filter are firmly connected. Do not remove the filter trough and the filter. Insert the probe directly into the soil to prevent the probe from being repairable Damage
2. Insert the probe part vertically into the soil, and the depth of insertion must at least cover the filter screen. Under normal circumstances, the pH value in the air is between 6.2 ~ 7.8;
3.After burying the sensor, pour a certain amount of water around the soil to be measured, wait a few minutes, and wait for the water to soak into the probe, then you can read the data on the instrument. Under normal circumstances, the soil is neutral and the pH value is between Around 7, the actual pH value of the soil in different places will be different, it should be determined according to the actual situation;
Precautions
1、The electrode lead is a special 4-core shielded wire, and customers are prohibited from splicing the lead without permission, and will not be responsible for the consequences;
2. Avoid long-term immersion in distilled water or protein solution, and prevent contact with silicone grease;
3. If the electrode is used for a long time, his glass film may become transparent or have deposits. At this time, it can be washed with dilute hydrochloric acid and rinsed with water;
4. When you do maintenance on the electrode, you still cannot do the calibration procedure and normal measurement, which indicates that the electrode can no longer respond, please replace the electrode
5. The PH electrode wire is not waterproof. Try to prevent the electrode wire from contacting water.
6. The life of the electrode is one year under normal use. Due to the harsh environment, improper maintenance of the goods will shorten it.
Use and maintenance
1. There is an appropriate amount of 3.3mol / L KCl solution in the protective cover at the front of the electrode, and the electrode tip is soaked to keep the glass bulb and liquid junction activated
2. When the electrode is used, it is necessary to remove the transparent protective cover at the front end and immerse the glass bulb and the liquid junction in the solution;
3. Before installation, be sure to use raw material tape (3/4 thread) for waterproof sealing work to prevent water from entering the PH electrode and causing short circuit of the PH electrode cable.
4. When measuring, it should be washed in distilled water (or deionized water), and dried with filter paper to prevent impurities from entering the electrode bulb in the test solution.The liquid junction should be completely immersed in the test liquid;
5. Check if the terminals are dry. If there is any contamination, please wipe with dry alcohol and blow dry before use;
6.users regularly clean the glass bulbs and liquid junctions in front of the electrodes, and regularly coordinate with the instrument for calibration;
7. The electrode should be washed when not in use and inserted into a protective cover with a saturated potassium chloride solution.
