Feature: 1. Strict manufacturing process is adopted to conduct waterproof and dustproof treatment on the entire body to ensure stable monitoring of components, and the protection level has reached IP68. 2. High quality 316 stainless steel, rust resistance, electrolytic resistance, salt and alkali corrosion resistance, to ensure the long-term use, it is suitable for all kinds of soil. 3. The sensor uses imported low-power MCU high-quality chips to ensure the sensor's low power consumption, high sensitivity, and stable signal transmission. 4. High‑density epoxy resin is used for high‑temperature vacuum filling between the probe and the body, which prevents moisture from entering the body to a large extent, and has better sealing performance. 5. Easy to measure, not only for professionals, but also for non-professionals, just insert the instrument into the soil to measure. Specification: Item Type: Soil Sensor Material: ABS+ 316 Stainless Steel Color: As shown in the picture Weight: Approx.213g/7.5oz Application: Comprehensive monitoring of various soil quality, suitable for agricultural greenhouses/flower breeding/green plant cultivation/grain storage, etc. Waterproof Rating: IP68 Temperature Accuracy: ±0.5℃ (25℃) DC Power Supply: DC 10-30V Equipment Power Consumption: ≤0.5W Output Signal: RS485 signal Conductivity Accuracy: ±3% Temperature Range: -40℃~+60℃ Moisture Range: 0%~ 100% Conductivity Range: 0-20000us/cm Quick Test Method: Select a suitable measurement location, avoid rocks and similar hard objects, plan the surface soil according to the required measurement depth, maintain the original slack of the soil below, hold the sensor firmly, and insert the soil vertically. It is recommended to average several times within a small range of the measuring point. Buried Measurement Method: Dig a pit with a diameter of about 20cm vertically, and insert the sensor steel needle horizontally into the pit according to the measurement needs, and fill the pit to ensure that the steel needle is in close contact with the soil. After the sensor is stable for a period of time, continuous long-term measurement can be carried out and record. (The detailed measurement method can refer to the instruction manual) .
