Product Description

The TEROS 10 is a low-cost ruggedized soil moisture sensor ideal for large sensor networks. Its 70-MHz frequency minimizes salinity and textural effects, making it accurate in most soil or soilless media. With a tough, epoxy body, the TEROS 10 is designed to withstand some of the harshest field conditions, which means problem-free measurements over the longevity of your research.

Features and Benefits

  • Low-cost, ruggedized soil moisture sensor.
  • Ideal for large sensor networks.
