Important Reminder The measurement adopts the general rapid detection method, so there are certain errors. Use with caution for planting reference. The sensor supports the function of writing data. You can use standard instruments to measure and then write the data in to provide information for a monitoring system. This sensor is for soil temperature, moisture, PH, and conductivity (EC) measurement. It is calibrated against high-precision sensors and the soil drying method for weighing. It offers high precision, fast response, and stable output. It is suitable for various soils with low salt content. It can be long-term buried in the soil and features long-term electrolysis resistance, vacuum potting, and is completely waterproof. Color: Black Material: ABS and Metal Functions and Features The sensor has a compact design for easy carrying, installation, operation, and maintenance.
