Volumetric Water Content(VWC) | Range | Mineral Soil Calibration:0.0000-0.5700 m³/m³(0%-57%VWC) |
Soilless Media Calibration:0.0000-0.6900 m³/m³(0%-69% VWC) | ||
Apparent Dielectric Permittivity (εa):1(air)to 80(water) | ||
NOTE:TheVWCrange is dependent on the media the sensor is calibrated to.Acustomcalibration will accommodate the necessary ranges for most substrates. | ||
Resolution | 0.0008 m³/m³(0.08% VWC) in mineral soils from 0-0.50 m³/m³(0%-50% VWC) | |
Accuracy | With standard calibration equation.0.03 m³/m³(3% VWC)tvpicalin mineralsoils that have solution electrical conductivity<10 dS/m | |
NOTE:With soil-specific calibration, ±0.02 m³/m³(±2% VWC) is typicalin any soil. | ||
