Specification
| MEASUREMENT SPECIFICATIONS | |
| Volumetric water content (VWC) | RANGE: Mineral soil calibration: 0−0.57 m3/m3 (0%−57% VWC) Soilless media calibration: 0–0.69 m3/m3 (0%−69% VWC) Apparent dielectric permittivity (εa): 1 (air) to 80 (water)NOTE: The VWC range is dependent on the media the sensor is calibrated to. A custom calibration 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: NOTE: With soil-specific calibration, ±0.02 m³/m³ ( ±2% VWC) is typical in any soil. |
