Soil Moisture Measurement - TDR 300
Manage water responsibily and reduce operating
expenses
When precision irrigation decisions count, TDR 300 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.
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.
Perfect for Researchers and Consultants! An internal data logger
and RS-232 port allow for use with a DGPS for geo-referenced soil
moisture measurements. Includes software and PC cable*.
RODS ARE SOLD SEPERATELY.
