TDR-310W Soil Moisture Sensor

A TDR (Time Domain Reflectometry) Soil Moisture Sensor is an advanced instrument used to measure the volumetric water content (VWC) of soils by sending a short electromagnetic pulse along waveguides (rods) embedded in the soil, and measuring the travel time or reflection of that pulse. The dielectric permittivity of soil changes significantly with water content, so this method enables accurate, non‑destructive measurement of soil moisture under a wide range of conditions.

These sensors are ideal for agriculture, irrigation management, environmental monitoring, and research applications where precise soil water data is required. They offer high accuracy, fast response, and stability across different soil types and salinity levels.
