WaterScout SM 100 Soil Moisture Sensors
The key is knowing both when and how much to water!
Maintaining a healthy soil moisture and water balance is essential for producing high quality plants. Under-watered plants suffer from nutrient deficiencies, stunting and wilting. Conversely, over-watered plants are more susceptible to disease pressure and less tolerant of dry conditions later on in their life cycle. Extreme over-watering will suffocate the plant and lead to root death.
Measures Volumetric Water Content (VWC) of soil
Capacitance-type sensor responds immediately to changes in soil moisture content for better irrigation decisions
Calibrated for mineral soils or soilless media
Installs easily into 3/4 in (1.9 cm) hole
Install permanently or use to take spot measurements
Can be read with the FieldScout® Soil Sensor Reader (Item 6466) or WatchDog® 2000 and 1000 Series Stations
Connect up to 8 sensors to one station Not compatible with 400/200 loggers. WatchDog Stations sold prior to 2009 must be upgraded. (call for support)
NEW Calibration feature: Sensors with "3/14" code can be re-calibrated using the FieldScout Soil Sensor Reader (item 6466) or the WaterScout Calibration Device (item 6470CAL3V). Please see the product manual for calibration proceedure.
