3-in-1 Soil Nutrient Meter- Portable NPK Analyzer

The Soil Nutrient Tester NPK Sensor is an advanced digital soil analysis device designed to measure essential soil nutrients—Nitrogen (N), Phosphorus (P), and Potassium (K)—directly in the field. Built with a rugged IP68-rated stainless-steel probe, this sensor enables farmers, agronomists, researchers, and greenhouse operators to monitor soil fertility in real time and make informed fertilizer management decisions. The sensor supports RS485 Modbus communication for seamless integration with IoT platforms, weather stations, and smart agriculture systems.Key Features - 3-in-1 Soil Nutrient Meter- Portable NPK AnalyzerReal-time measurement of Nitrogen (N), Phosphorus (P), and Potassium (K)High-precision digital sensing technologyWide measurement range up to 1999 mg/kgFast response time for instant field readingsDurable stainless-steel probe constructionIP68 waterproof and dustproof protectionRS485 Modbus communication protocolLow power consumption for long-term deploymentSuitable for smart farming and IoT integrationEasy installation and maintenance-free operation
