FieldScout TDR 300 Soil Moisture Meter
Spectrum FieldScout TDR 300 Soil Moisture Meter

Product Features
  • 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.
  • Equipped with internal data logger and RS-232 port.
  • Records 3,250 measurements (1,350 with added GPS/DGPS option).
  • Configure and download meter with FieldScout software (included).
  • Compatible with SpecMaps online web-mapping application.
  • Includes soft-sided carrying case.
  • Rods sold separately
  • New calibration feature added in 2012.
  • Garmin GPS 72H Handheld GPS Navigator recommended. 
  • Spectrum’s PC cables connect to a 9-pin serial port. USB-Serial adapterrequired for connection to computers with only USB ports.
  • GPS interface requires two cables. The GPS/DGPS cable is available from Spectrum. 
  • A PC serial interface cable supplied by the manufacturer of the GPS receiver is also required.

Jet Fill Tensiometers
Soil Moisture Jet Fill Tensiometers

Product Features
  • Direct measurement of soil water tension.
  • Allows easy replacement of the ceramic cup and dial gauge, and addition of extension tubes and the Service Cap.
  • Soil Moisture Jet Fill Tensiometers available in a variety of lengths, ranging from 6 inches (15 cm) to 60 inches (1.5 m).
