Important Reminder The measurement adopts general rapid detection methods, so there may be some error. Use with caution for planting reference. However, the sensor supports data writing function. You can use standard instruments to measure and then input the data for the monitoring system. The sensor is designed for soil temperature, moisture, pH, and conductivity (EC) measurement. Compared with original German high-precision sensors and soil drying weighing calibration methods, it offers high precision, fast response, and stable output. Suitable for various soil types with low salt content. Can be buried in soil long-term, resistant to electrolysis and corrosion, vacuum potted, and fully waterproof. Color: Black Material: ABS + Metal Functions and Features (1) Compact design, easy to carry, install, operate, and maintain. (2) Reasonable structural design ensures stainless steel probe longevity. (3) Minimizes soil disturbance, widely applicable. (4) High measurement accuracy, reliable performance, and proper operation. (5) Fast response and high data transmission efficiency. Applicable to water-saving irrigation, greenhouse vegetables, flowers, gardening, grass pastures, soil speed measurement, plant cultivation, and scientific testing.
