Soil NPK Sensor

Soil npk sensor description

The soil npk sensor is suitable for detecting the content of nitrogen, phosphorus, and potassium in the soil, and judging the fertility of the soil. thereby facilitating the systematic evaluation of the soil condition. Can be buried in the soil for a long time, resistant to long-term electrolysis, corrosion resistance, vacuum potting, and completely waterproof. Soil npk sensors are widely used in soil nitrogen, phosphorus and potassium detection, precision agriculture, forestry, soil research, geological prospecting, plant cultivation and other fields.


(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.


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.
