IQSS-NPK Soil NPK sensor RS485, Nitrogen, Phosphorus and Potassium, 2m Cable
IQSS-NPK Soil NPK sensor RS485, Nitrogen, Phosphorus and Potassium, 2m Cable
IQSS-NPK soil NPK sensor, also known as the soil nutrient quick tester to detect the content of nitrogen, phosphorus and potassium in the soil. By detecting the contentof nitrogen, phosphorus and potassium in the soil, it can judge the fertility of the soil, and then it is convenient to evaluate the soil condition systematically. The sensor rapid measurement method actually measures the electrical conductivity of the soil, and its principle is to multiply the measured electrical conductivity value by the corresponding coefficient as the value of nitrogen, phosphorus, and potassium content. The sensor is widely used in the detection of soil nitrogen, phosphorus and potassium precision agriculture, forestry, soil research, geological exploration, plant cultivation and other fields.
