How does soil npk sensor work?

User:JXCTUpload time:Jul 25 2022
Soil NPK Sensor

Soil NPK sensor is a kind of soil detection instrument used to detect the content of nitrogen, phosphorus and potassium in the soil, and judge the soil fertility by detecting the content of N, P and K in the soil. The stainless steel probe of the soil sensor can be buried in the soil for a long time, resistant to long-term electrolytic, salt, alkali corrosion. The enclosure is vacuum sealed and completely waterproof.

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 nutrient sensors are widely used in soil nitrogen, phosphorus and potassium detection, precision agriculture, forestry, soil research, geological prospecting, plant cultivation and other fields.

NPK sensor features

1, Simple to use, few operation steps, fast measurement, no reagents, unlimited detection times.

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

3, The electrode is made of specially treated alloy material, which can withstand strong external impact and is not easy to damage.

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

5, The probe plug-in design ensures accurate measurement and reliable performance.
