Description：
The soil nitrogen, phosphorus and potassium sensor(soil NPK sensor) is suitable for detecting the content of nitrogen, phosphorus and potassium in the soil, and judging the fertility of the soil by detecting the content of nitrogen, phosphorus and potassium in the soil, thereby facilitating the customer’s systematic assessment of the soil condition. The sensor is suitable for all kinds of soil, can be buried in the soil for a long time, is resistant to long-term electrolysis, corrosion resistance, vacuum potting, and completely waterproof.
Features：
(1)Convenient measurement: soil nitrogen, phosphorus and potassium detection is no longer limited to the industry, the instrument can be inserted into the soil to measure;
(2)Low cost: compared with the traditional laboratory measurement, (3)soil NPK sensor has the advantages of low threshold, low cost, less steps, no reagent and unlimited detection times;
High precision, high resolution: high precision, fast measurement speed, can reach 2% accuracy, increased stability. The resolution is as high as 1mg / kg (mg / L), and it is easy to carry，The data can be retrieved by inserting the soil, which shortens the time cost.
Monitoring parameters：
Soil NPK detection:Test at any time,Soil NPK is an important nutrient element for plant growth and promotes plant growth.
Application：
Soil sensor is suitable for farmland production, soil research, greenhouse planting, orchard nursery, all kinds of horticultural soil testing, support parameter free customization, multi in one soil sensor customization.
