FieldScout TDR 300 Soil Moisture Meter

Manage water responsibly and reduce operating expenses.

 
When precision irrigation decisions count, the FieldScout TDR Soil Moisture Meter Series offers growers a tool to eliminate the guesswork. Based on proven time-domain measurement technology, these portable units accurately measure soil moisture across the full range of soil moisture conditions. Select from the 1.5, 3, 4.8 or 8-inch (3.8, 7.5, 12 or 20-cm) probe rods to suit your desired depth measurement. Install PVC access tubes and take readings deeper in the soil profile for permanent crops like apple, grapes, and nut crops.
 
The TDR 300 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. Create up to 2 management sites based on your soil types and crop needs. Use the raw reading mode (measurement period in microseconds) to do soil-specific calibrations.

CALIBRATION FEATURE - If you purchased your meter before 2012, the TDR family of soil moisture meters now includes the option to perform a calibration on an individual meter.  The calibration is done in 2 media; air and distilled water.  This new feature took effect with firmware version 6.5 and is included with units shipped after January 1, 2012 (purchased directly thru Spectrum). Meters with firmware versions earlier than v. 6.5 can be upgraded by purchasing and installing an updated microcontroller chip (Item #CHIP-TDR3, see above table for purchasing). See Calibration Feature of FieldScout TDR Meters for more details. Firmware version 6.5 or higher required for FieldScout Bluetooth Device connection

The GPS 72H is a low-cost solution designed to provide precise GPS positioning using correction data obtained from the Wide Area Augmentation System (WAAS). The GPS 72H can provide position accuracy to less than three meters when receiving WAAS corrections. This rugged, waterproof, unsinkable GPS receiver offers a large, 4-level grayscale screen. It's designed as the next generation in basic, entry-level Garmin GPS. A PC serial interface cable supplied by the manufacturer of the GPS receiver is also required, this is also available on Amazon.com
