Accurate Moisture and Salinity Measurement in Selected Soil Profiles

IMKO GmbH (Germany) has launched a brand new profile probe for the development of soil-water balance models, irrigation control and salt content testing at different soil depths. In order to measure precise selected soil horizons, PICO-PROFILE can be configured easily. The modular design allows to arrange up to 10 measurement segments PICO-T3P in such a way that different soil depths on the very interesting soil profile locations can be measured. Each PICO-T3P segment can be adjusted to the particular soil horizon concerning the calibration.

The revolutionary 1GHz TRIME-radar technology (Time-Domain-Reflectometry), allows a precise determination of the moisture and the salt content in soils. PICO-PROFILE in addition to measuring soil moisture, measures the electrical conductivity EC of the soil, whereby the determination of the salt content in each soil horizon is possible. The measurement result can be calculated to the pore water conductivity ECw or respectively to TDS (mg of salt per liter water). With a representative measurement field PICO-PROFILE penetrates deep into the soil around the access tube.

Only a large measurement field guarantees a representative measuring. Each PICO-T3P segment measures 1dm3 ground. The Rugged design guarantees a long-term operation in harsh environments. Attractive price/performance ratio compared to conventional sensors allows the use of several measuring segments PICO-T3P per measurement point.

An RS485 interface or optional SDI12 interface allows data acquisition with external data loggers.
