NPK Sensor(SMKB-SNPK)
Soil nitrogen, phosphorus and potassium sensor is suitable for detecting the content of nitrogen, phosphorus and potassium in soil. It can judge the fertility degree of soil by detecting the content of nitrogen, phosphorus and potassium in soil, thus facilitating the systematic evaluation of soil conditions by customers.
Scope of Application
It is widely used in paddy field, greenhouse planting ,rice , vegetable planting , orchard nursery , flower and soil research, etc
Buried measurement
Dig a hole with a diameter of more than 20cm vertically , insert the steel needle of the sensor horizontally into the wall of the hole at a given depth, fill the hole tightly , and measure and record it for several days, months or even longer after it is stabilized for a period of time.
Surface Instant Measurement
Choose a suitable measurement site, avoid rocks, and ensure that the steel needle will not hit anything hard. Cut the topsoil according to the required measuring depth to maintain the original tightness of the soil below . Hold the sensor and insert it vertically into the soil, do not move it from side to side during insertion. Multiple measurements and averaging are recommended for a small range of measurement points.
