WaterScout SM 100 Soil Moisture Sensor
The key is knowing both when and how much to water!
Maintaining 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
- The 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)
