RS485 5Pin Soil PH NPK Temperature and Humidity EC Sensor Conductivity Detector Tester

Feature: 1. The soil comprehensive sensor creatively measures the seven parameters of conductivity, moisture, temperature, ph, and nitrogen, phosphorus and potassium, which greatly facilitates your systematic assessment of soil conditions. 2. The sensor has high accuracy, quick response, stable output, and is less affected by the salt content of the soil. It is suitable for all kinds of soil. 3. It can be buried in the soil for a long time, is resistant to long?term electrolysis and corrosion, and uses high?density epoxy resin for vacuum potting, which can prevent moisture from entering the inner of the fuselage and has good sealing performance. 4. The probe is made of special metal material, which is resistant to rust, electrolysis, and salt?alkali corrosion, ensuring the long?term operation of the probe part. 5. It is suitable for scientific experiments, water?saving irrigation, greenhouses, flowers and vegetables, grassland pastures, soil rapid testing, plant cultivation, sewage treatment, grain storage, and measurement of various particulate water content and temperature. Specification: Condition: 100percent Brand New Item Type: Soil Sensor Material: Plastic+Steel+Epoxy Color: As shown in the picture Size: Approx.13.8x4.5cm/5.4x1.8in Weight: Approx.290g/10.2oz Power Supply: 12-24V DC Output Signal: RS485 Temperature Measurement Range: -40 celsius -80 celsius Temperature Accuracy: +/-0.5 celsius Temperature Resolution: 0.1 celsius Moisture Measurement Range: 0-100percent Moisture Accuracy: +/-3percent within the range of 0-53percent ; +/-5percent within the range of 53-100percent Moisture Resolution: 0.10percent Conductivity Measurement Range: 0-10000us/cm Conductivity Resolution: 10us/cm pH Measurement Range: 3-9pH pH Measurement Accuracy: +/-0.3pH pH Resolution: 0.01pH Measuring Range of Nitrogen, Phosphorus and Potassium: 0-1999mg/kg NPK Measurement Accuracy: +/-2percent F.s Resolution of NPK: 1mg/kg (mg/l) Storage Environment: -20 celsius -60 celsius Working Pressure Range: 0.9-1.1atm Response Time: <1s Protection Level: IP68 Installation Method: All buried or all probes inserted into the measured medium Precautions: 1. All steel needles must be inserted into the soil during measurement. 2. Avoid strong sunlight directly shining on the sensor and cause excessive temperature. Pay attention to lightning protection in the field. 3. Do not bend the steel needle violently, pull the wire of the sensor forcefully, and do not hit or hit the sensor violently. 4. The sensor"s protection grade is IP68, so the entire sensor can be soaked in water. 5. Due to the existence of radio frequency electromagnetic radiation in the air, it is not suitable to stay in the air for a long time with electricity. 6. Please be careful not to connect the wrong wiring sequence, the wrong wiring will cause the equipment to burn. . Package List: 1 x Soil Sensor1 x Manual Note: 1.
