Spectrum FieldScout TDR 300 Soil Moisture Meter

 
FieldScout TDR 300 Soil Moisture Meter
 
  • Spectrum FieldScout TDR 300 Soil Moisture Meter has two volumetric water content modes; one for standard soils and one for higher clay soils.
  • In volumetric water content (VWC) mode, the meter converts a measured electrical signal into percent soil moisture content using an equation valid over a wide range of mineral soils.
  • In irrigation mode, the meter displays a relative water content (RWC) on a scale of 0 to 100 corresponding to a user-defined upper and lower soil moisture reference level.
  • Water deficit, the amount of water needed to bring the soil moisture content up to the upper reference level, is also calculated and displayed.
  • The reference levels are easily programmed into the meter with the accompanying software.
  • Can create up to 2 management sites based on soil types and crop needs.
  • Use the raw reading mode (measurement period in microseconds) to do soil-specific calibrations.
  • Instantaneous readings of root zone soil moisture.
  • Connects to any GPS receiver with serial output.
