1The 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 longterm electrolysis and corrosion, and uses highdensity 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 saltalkali corrosion, ensuring the longterm operation of the probe part. 5It is suitable for scientific experiments, watersaving 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.1 x Soil Sensor1 x Manual
