The TDT Sensor.

The Acclima Digital TDT® Soil Moisture Sensor represents a revolutionary advance in the irrigation industry and is now available as a research tool. Calibration-free accuracy & stability.

Data Captured:

  1. Absolute volumetric water content (% VWC)

  2. Soil Temperature

  3. Soil Conductivity

  4. Soil Permittivity

 

Revolutionary Technology

The digital soil moisture sensor is a very effective tool to log moisture data for a variety of applications.

It is the first moisture sensor to incorporate the accuracy of digitized Time Domain Transmissometry in a low-cost instrument, providing highly accurate absolute readings of soil moisture under all conditions of temperature and soil chemistry under which crops will grow.

Features:

 

  • Absolute VWC accuracy ±2%

  • Operates in all soils

  • Large 100 ml soil sample volume

  • No maintenance, simple installation

  • 316 stainless steel construction 20+ years life

  • Moisture readings remain stable with changes in salinity, soil chemistry and temperature.
