1. The three parameters of soil Nitrogen, phosphorus and potassium are combined into one.
2. Low threshold, few steps, fast measurement, no reagents, unlimited detection times.
3. The electrode is made of specially processed stainless steel, which can withstand strong external impact and is not easy to damage.
4. Completely sealed, resistant to acid and alkali corrosion, can be buried in soil or directly into water for long-term dynamic testing.
5. High precision, fast response, good interchangeability, probe plug-in design to ensure accurate measurement and reliable performance.
The sensor is designed for soil monitoring, water-saving irrigation, floriculture, greenhouses, flowers and vegetables, grassland pastures, soil rapid testing, plant cultivation, scientific experiments, sewage treatment, precision agriculture and other occasions.
