Tech bulletin

WaterScout SMEC300 measures Soil Moisture, Electroconductivity (EC/Salts) and Temperature. Whether you are measuring potted plants in a greenhouse or turf on a putting green, knowing the salinity of the root zone is critical for healthy plant growth. Irrigation, fertilizers and crop depend all impact salt concentrations. High levels can damage the plant, low levels can lead to nutrient deficiencies. The SMEC300 sensor is a capacitance type soil moisture sensor and responds immediately to changes in soil moisture content of better irrigation decisions. Carbon ink electrodes provide a large measuring surface for electrical conductivity (EC) and calibration is simple! You can connect up 4 sensors, depending on the weather station you are connecting to. Data can be read with the FieldScout Soil Sensor Reader (Item #6466) WatchDog App, SpecConnect, SpecWare (Includes a 20' (6.1m) Cable)
