Thank you for purchasing the Field Scout
TM
TDR 150
soil moisture, electrical conductivity and soil surface
temperature 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. The meter also
measures soil surface temperature. The user can quickly
transition between taking VWC readings in standard
and high-clay mode.
The meter’s built-in data logger eliminates the need to
record data manually. The data points can be viewed
with the FieldScout Mobile app that maps out soil
measurements using logged location coordinates (see p.
27). Measurements can also be saved to a USB drive
that is plugged into the built-in USB port. The meter
can be upgraded (item 6445GBU) to activate Bluetooth
and GNSS.
