Important Reminder The measurement of adopts the general rapid detection , so there are certain error, Use with caution suitable for planting reference. However, the sensor supports the function of writing data. You can use standard instruments to measure then write in to provide data suitable for monitoring system. sensor is suitable for soil temperature and moisture, PH, conductivity (EC),measurement, compared with the original German high-precision sensors and soil drying of weighing the actual calibration, high precision, fast response, stable output. By the soil salt content of small, suitable suitable for all kinds of soil. Long-term buried in the soil, resistant to long-term electrolysis, corrosion resistance, vacuum potting, completely waterproof. color: Black Material: ABS+metal Functions and Features (1) The sensor compact design, easy to carry, installation, operation and maintenance. (2) reasonable structure design, stainless steel probe life assurance. (3) soil less affected areas are widely used. (4) High measurement accuracy, reliable persuitable for mance, proper operation (5) fast response, high data transmission efficiency. Applicable to of water-saving irrigation, greenhouse vegetables, flowers, gardening, grass pastures, soil-speed measurement, plant cultivation, scientific testing.
