NPK Soil Sensor, Needle Probe Design for Soil Moisture Conductivity Meter for Agriculture

General Description: The NPK soil sensor is a portable instrument designed to measure soil moisture, temperature, and conductivity. Its stainless steel needle probe ensures good corrosion resistance and durability. With high measurement accuracy and a low-power LCD screen, it allows for real-time monitoring of soil composition, detecting various organic components without the need for reagents. This sensor is ideal for farmers and agricultural researchers. Technical Specifications Item Type: Soil Temperature, Humidity, and Conductivity Sensor Weight: Approx. 209 g Product Size: Approx. 18.6 cm Power Supply: 3 AA Batteries (Not Included) Working Time: Up to 20 uses per day for 1.3 years Static Current: < 50 μA Average Operating Current: 13 mA Response Time: < 1 second Operating Temperature: -20℃ to 60℃ Protection Rating: IP54 Temperature Measurement Range: -40℃ to 80℃ Temperature Resolution: 0.1℃ Temperature Accuracy: ±0.5℃ (at 25℃) Humidity Measurement Range: 0-100% Humidity Resolution: 0.1% Humidity Accuracy: 2% between 0 and 50%, 3% between 50 and 100% Conductivity Measurement Range: 0-10000 µS/cm Conductivity resolution: 1 µS/cm Conductivity accuracy: ±3% Usage To ensure accurate measurements, it is recommended to: Ensure full contact of the probe with the ground. Avoid testing unsuitable materials such as dry flour or small stones. Take the average value from several tests to improve accuracy. Clean the probe after use to prevent oxidation. Other information
