Thank you for purchasing the Field Scout
TM
TDR 250
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 250’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.
Measurements can be saved to a USB flash drive using
the built-in USB port.
