Feature: 1. The whole sensor body is treated with waterproof and dustproof to ensure the normal operation of components for a long time. The waterproof and dustproof grade can up to IP68. 2. The soil conductivity sensor is suitable for the measurement of total soil salinity (conductivity), which greatly facilitates the evaluation of soil conditions by the customer. 3. High precision, quick response, stable output, suitable for all kinds of soil. 4. It can be buried in the soil for a long time, resistant to long-term electrolysis, corrosion resistance, vacuum filling and sealing, completely waterproof. 5. It is widely used in scientific experiments, water-saving irrigation, greenhouse, flowers and vegetables, grassland pasture, soil rapid measurement, plant culture, sewage treatment, electrical conductivity measurement.
