ECH2O 10HS Tech Specs
TECHNICAL SPECIFICATIONS
Volumetric Water Content
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:Â 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
With standard calibration equation, 0.03 m³/m³ (3% VWC) typical in mineral soils that have solution electrical conductivity <10 dS/m
NOTE: With soil-specific calibration, ±0.02 m³/m³ ( ±2% VWC) is typical in any soil.
METER data loggers (ZL6, EM50/60 series, Em5b) or any data acquisition systems capable of switched 3–15 VDC excitation and single-ended voltage measurement at greater than or equal to 12-bit resolution.
