HS-NPK-4-20MA Soil nitrogen, phosphorus and potassium sensors (4 ~ 20mA type)
The soil nitrogen, phosphorus, and potassium three-in-one fertility sensor is suitable for detecting the content of nitrogen, phosphorus, and potassium in the soil, and determining the fertility of the soil by detecting the content of nitrogen, phosphorus, and potassium in the soil, thereby facilitating the systematic assessment of the soil condition. Can be buried in the soil for a long time, resistant to long-term electrolysis, corrosion resistance, vacuum potting, completely waterproof.
The sensor is widely used in soil nitrogen, phosphorus, potassium detection, precision agriculture, forestry, soil research, geological exploration, plant cultivation and other fields.
Features
Low threshold, few steps, fast measurement, no reagents required, unlimited detection times.
High measurement accuracy, fast response speed and good interchangeability.
The electrode is made of a specially treated alloy material, which can withstand strong external force and is not easy to be damaged.
Completely sealed, resistant to acid and alkali corrosion, can be buried in the soil for long-term dynamic testing.
Probe insertion design ensures accurate measurement and reliable performance.
