PICO-32 Soil Moisture Sensor

PICO-32 Soil Moisture Sensor Moisture Measurement in Soil, Sand and Concrete Highest accuracy by the use of the latest TDR electronics Measure direct 0...100% vol. soil water content NEW: Measures 3 important parameters: water content temperature electrical conductivity and salinity NEW: with SDI-12 interface Bulk soil electrical conductivity up to 12dS/m small measurement volume > 250ml Rods exchangeable Bottom of Form TRIME-PICO32 sensor with internal TDR-electronics IMKO‘s intelligent rod probes are highly sophisticated high-tech devices and extremely robust. A unique feature is their integrated TDR electronics, thus achieving the greatest accuracy and best networking capability e.g. digital network cable lengths of up to 3 km are possible for the IMP-Bus version. In contrast to other methods TRIME®-PICO is less effected by disturbing variables such as temperature or electrical conductivity. An integrated temperature sensor gives valuable additional information. For in situ monitoring of volumetric moisture in soils and other porous materials. The large measuring volume is particularly suitable for applications in heterogeneous and skeletal media. Burying capability for both horizontal and vertical orientation. Due to its mechanical robustness TRIME®-PICO32 is recommended for mobile use together with Bluetoothmodule PICO-BT. TRIME-PICO32 is the sensor for maximum accuracy in materials with bulk electrical conductivity of up to 12dS/m. Ideal for irrigation control systems and soil moisture monitoring Perfect for sandy and loamy soils
