- Soil Moisture Sensors


In order to measure precise selected soil horizons, PICO-PROFILE can be configured easy and modular directly at site installation. The modular design allows to arrange up to 10 measurement segments PICOT3P in such a way that different soil depths on the very interesting soil profile locations can be measured. Each PICO-T3P segment can be set to the particular soil horizon concerning the calibration. Calibration curves for sand, loess or clay are already stored in the measuring segment PICO-T3P and provide even higher precision in the measurement of the moisture content. 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.
Rugged and waterproof 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 analogue-output-board allows data acquisition with external data loggers.
