PICO-PROFILE Soil Moisture Sensor
Ideal for the development of soil-water balance models, irrigation control and salt content testing at different soil depths
Simple and modular configuration
Connection of data logger via GPRS wireless modem
Rugged design
Attractive price / performance ratio
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.
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. Each PICO-T3P segment measures 1dm3 ground.
PICO-PROFILE can be easy connect to the data logger globeLog which allows battery operation for long term storage of data. Optionally, the use of GPRS radio modem and SIM card is possible.
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.
