High Precision Soil NPK Sensor for Fertilizer Testing – Portable Intelligent Soil Nutrient Detector with ±2% Accuracy and 1mgkg Resolution

This high-precision Soil NPK Sensor is engineered for accurate, real-time measurement of essential soil nutrients—nitrogen (N), (P), and potassium (K)—to support optimal plant growth.FAQ:1. How do I use the sensor correctly? Insert the stainless steel probe fully into moist soil; avoid dry or rocky ground. Do not expose to direct sunlight or thunderstorms during operation.2. Can the sensor be submerged in water? Yes, it features an IP68 protection rating, making it and suitable for wet environments.3. Why should I avoid powering the sensor in air for long periods? Ambient frequency interference may affect signal stability; always use with the probe inserted in soil.Designed for farmers, agronomists, and gardening enthusiasts, this tool enables data-driven soil management without complex calibration.
