Thank you for purchasing the Field Scout
TM
TDR 350
soil moisture meter. This manual describes the meter's
general features and operation.
Soil moisture is a critical, and potentially highly varia-
ble, component of the soil environment. Time domain
reflectometry is a proven technology for quickly and
accurately determining volumetric water content
(VWC) in soil. Electrical conductivity (EC) is a func-
tion of the moisture and salt in the soil and can be fac-
tored out to increase the accuracy of VWC measure-
ments. The meter also measures soil surface tempera-
ture. The user can quickly transition between taking
VWC readings in standard, high
-
clay, and sand soils.
The TDR
350’
s shaft
-
mounted probe allows the user to
take measurements while standing. The meter
’
s built
-
in
data logger eliminates the need to record data manually.
The data points can be viewed with the FieldScout Mo-
bile app that maps out soil measurements using logged
location coordinates. Measurements can also be saved
to an external USB flash drive when plugged into the
built
-
in USB port.
