Product Description
Veinasa-NPK 3 in 1 High precision RS485 Output Analyzer for Soil NPK Sensor Fertilizer for Agriculture
Veinasa-NPK 3 in 1 High precision RS485 Output Analyzer for Soil NPK Sensor Fertilizer for Agriculture is suitable to detect the content of N, P and K in the soil. By detecting the content of N, P and K in the soil, we can judge the fertility of the soil, so as to facilitate the systematic assessment of the soil conditions. It can be buried in the soil for a long time, resistant to long-term electrolysis, corrosion, vacuum filling and sealing, completely waterproof.
Functional features:
1) The threshold is low, the steps are few, the measurement is fast, no reagent is needed, and the number of detection is unlimited.
2) High measurement accuracy, fast response and good interchangeability.
3) The electrode is made of alloy material with special treatment, which can bear strong impact of external force and is not easy to be damaged.
4) Completely sealed, acid and alkali resistant, it can be buried in the soil for long-term dynamic detection.
5) The probe insertion design ensures accurate measurement and reliable performance.

Using methods:
1. Quick measurement method
Select a suitable measurement location, avoid stones, ensure that the steel needle will not touch hard objects, throw away the top soil according to the required measurement depth, maintain the original tightness of the soil below, firmly grasp the sensor and insert it vertically into the soil, and do not shake left and right when inserting, it is recommended to measure and average multiple times within a small range of a measurement point.
2. Buried measurement method
Dig a pit with a diameter of more than 20cm vertically, insert the sensor steel needle horizontally into the pit wall at a given depth, fill the pit tightly, and after a period of stability, the measurement and record can be carried out for several days, months or even longer.
Precautions:
1. During the measurement, the steel needle must be inserted into the soil completely.
2. Avoid high temperature caused by direct sunlight on the sensor. Pay attention to lightning protection during field use.
3. Do not bend the steel needle by force, do not pull the sensor lead by force, do not hit or hit the sensor by force.
4. The sensor protection grade is IP68, which can soak the whole sensor in water.
5. Due to the existence of radio-frequency electromagnetic radiation in the air, it is not suitable to be electrified in the air for a long time.
