Wireless Soil Temperature, Moisture, and Conductivity Three-in-One IDM-RD12 This transmitter is suitable for measuring soil temperature, moisture, and conductivity values. It is calibrated through comparison with sensors and the actual soil drying and weighing method, ensuring high accuracy, fast response, and stable output. It is less affected by soil salinity and suitable for various soil types. It can be buried in soil for long-term use, resistant to long-term electrolysis, corrosion, vacuum-sealed, and fully waterproof. Suitable for various environments, especially for soil, sewage treatment, and other applications.
