Description：
The soil NPK sensor is suitable for detecting the content of nitrogen, phosphorus, and potassium in the soil, and judging soil fertility by detecting the content of nitrogen, phosphorus, and potassium in the soil, thereby facilitating the systematic assessment of the soil condition by customers. The sensor is suitable for various soils, can be buried in the soil for a long time, is resistant to long-term electrolysis, corrosion resistance, vacuum potted plants, and is completely waterproof.
Features：
(1) Convenient measurement: The detection of soil nitrogen, phosphorus, and potassium is no longer limited to the industry, and the instrument can be inserted into the soil for measurement;
(2) Low cost: Compared with traditional laboratory measurement, (3) Soil NPK sensor has the advantages of low threshold, low cost, few steps, no reagents, unlimited detection times, etc.;
High precision and high resolution: high precision, fast measurement speed, accuracy up to 2%, stability increased. The resolution is up to 1mg/kg (mg/L), it is convenient to carry, and the data can be retrieved by inserting the soil, which reduces 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：
The soil sensor is suitable for farmland production, soil research, greenhouse planting, orchard nursery, all kinds of horticultural soil detection, supports free customization of parameters, and more than one soil sensor customization.
