Soil NPK Sensor
The soil nitrogen, phosphorus, and potassium three-in-one fertility sensor is suitable for detecting the content of nitrogen, phosphorus, and potassium in the soil, and determining the fertility of the soil by detecting the content of nitrogen, phosphorus, and potassium in the soil, thereby facilitating the systematic assessment of the soil condition. Can be buried in the soil for a long time, resistant to long-term electrolysis, corrosion resistance, vacuum potting, completely waterproof.
FEATURES:
1) Low threshold, few steps, fast measurement, no reagents required, unlimited detection times.
2) High measurement accuracy, fast response speed and good interchangeability.
3) The electrode is made of a specially treated alloy material, which can withstand strong external force and is not easy to be damaged.
4) Completely sealed, resistant to acid and alkali corrosion, can be buried in the soil for long-term dynamic testing.
5) Probe insertion design ensures accurate measurement and reliable performance.

�.Instructions
1.1 Quick test method
Select a suitable measurement location, avoid stones, and ensure that the steel needle does not touch hard objects. Discard the topsoil according to the required measurement depth, and maintain the original tightness of the soil below. Hold the sensor vertically and insert it into the soil. It is not allowed to shake left and right, it is recommended to measure multiple times to find the average value within a small range of one measurement point.
1.2 Buried survey
Vertically dig a pit with a diameter of> 20cm, insert the sensor steel needle horizontally into the pit wall at a predetermined depth, bury the pit tightly, and stabilize it for a period of time, then you can perform continuous measurement for several days, months, or even longer.
1.3 Precautions
1). All steel needles must be inserted into the soil during measurement.
2). Avoid direct sunlight on the sensor, which will cause excessive temperature. Pay attention to lightning protection in the field.
3). Do not bend the steel needle violently, do not pull the sensor lead wire with force, and do not beat or violently hit the sensor.
4). The protection grade of the sensor is IP68, which can soak the sensor in water.
5). Due to the presence of radio frequency electromagnetic radiation in the air, it should not be energized in the air for a long time.
Application
The sensor is widely used in soil nitrogen, phosphorus, potassium detection, precision agriculture, forestry, soil research, geological exploration, plant cultivation and other fields.
