WaterScout SM 100 Soil Moisture Sensor - Product Manuals
The sensor is made up of two electrodes that function as a capacitor, with the surrounding soil serving as the dielectric. An 80 MHz oscillator drives the capacitor and a signal proportional to the soil’s dielectric permittivity is converted to the output signal. The dielectric permittivity of water is much greater than air, soil minerals and organic matter. So, changes in water content can ...

WaterScout - Model SM 100 - Soil Moisture Sensor - SpecSheet
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 ...

Eijkelkamp - EC-Probe for Soil Conductivity Measurements - Manual
The standard EC-probe set for soil conductivity measurements consists of an EC-probe and an earth resistivity meter. It is used to measure electric resistivity of the soil, which is an indicator of soil salinity. The EC-probe can be operated at a depth of up to 110 cm. Salinization means an increased salt concentration of the soil. The occurrence of salt in rooted soil impedes the water ...
