High-precision intelligent soil nutrient detector and NPK tester sensor.

1. Easy to measure, suitable for both professionals and non-professionals; simply insert the instrument into the soil to be measured. 2. High precision, fast measurement speed, accuracy up to 2%, and increased stability for more accurate data. 3. Resolution up to 1 mg/kg (mg/l), enabling quick on-site inspection. Easy to carry and read simply by inserting it into the soil. 4. Portable measurement provides a precise understanding of soil fertility. Users can measure soil conditions at any time, and based on the soil's condition, soil fertility can be balanced to create a suitable growing environment for plants. 5. The sensor uses a high-quality chip, resulting in low power consumption, high sensitivity, and a stable signal. 6. IP68 waterproof and dustproof rating ensures normal operation of the components for extended periods. Good sealing performance prevents moisture from entering the instrument. 7. High-quality probe, rust-resistant, electrolytically resistant, and resistant to salt and alkali corrosion, ensuring long-term operation of the probe component. Therefore, it is suitable for all soil types. 8. Suitable for agricultural production, greenhouse breeding, orchard nurseries, and soil research. 9. Suitable for detecting alkaline soil, acidic soil, substrate soil, seedbed soil, and coconut husk soil. Specification: Condition: 100% Brand New Item Type: Soil NPK Sensor.
