Features1The 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. 2The 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. 3It 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. 4The 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. 5It 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.SpecificationCondition: 100% Brand NewItem Type: Soil SensorMaterial: Plastic+Steel+EpoxyColor: As shown in the pictureSize: Approx.13.8x4.5cm/5.4x1.8inWeight: Approx.290g/10.2ozPower Supply: 12-24V DCOutput Signal: RS485Temperature Measurement Range: -40-80Temperature Accuracy: 0.5Temperature Resolution: 0.1Moisture Measurement Range: 0-100%Moisture Accuracy: 3% within the range of 0-53%; 5% within the range of 53-100%Moisture Resolution: 0.10%Conductivity Measurement Range: 0-10000us/cmConductivity Resolution: 10us/cmpH Measurement Range: 3-9pHpH Measurement Accuracy: 0.3pHpH Resolution: 0.01pHMeasuring Range of Nitrogen, Phosphorus and Potassium: 0-1999mg/kgNPK Measurement Accuracy: 2%F.sResolution of NPK: 1mg/kg (mg/l)Storage Environment: -20-60Working Pressure Range: 0.9-1.1atmResponse Time:
