npk sensor

1.npk sensor product overview

npk sensor is used to measure the levels of nitrogen, phosphorus and potassium (NPK). Monitoring the content of nitrogen (N), phosphorus (P) and potassium (K) in the soil helps determine the fertility of the soil.npk sensor is suitable for detecting the content of nitrogen, phosphorus and potassium in the soil.By detecting the content of nitrogen, phosphorus and potassium in the soil, the fertility of the soil can be judged, thereby facilitating the systematic assessment of soil conditions.It can be buried in the soil for a long time, is resistant to long-term electrolysis, corrosion resistance, vacuum potting, and is completely waterproof.

The sensor is widely used in soil nitrogen, phosphorus and potassium detection, precision agriculture, forestry, soil research, geological exploration, plant cultivation and other fields.

2.Functional characteristics of npk sensor

1.Low threshold, few steps, fast measurement, no reagents required, and no limit on the number of tests.

2.High measurement accuracy, fast response speed and good interchangeability.

3.The electrodes are made of specially treated alloy materials, which can withstand strong external impacts and are not easily damaged.

4.Completely sealed, resistant to acid and alkali corrosion, and can be buried in the soil for long-term dynamic testing.

5.The probe insertion design ensures accurate measurement and reliable performance.
