| VOLUMETRIC WATER CONTENT (VWC) |
Range:
Mineral soil calibration: 0.00–0.70 m3/m3
Soilless media calibration: 0.0–1.0 m3/m3
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:
0.001 m3/m3
Accuracy:
Generic calibration: ±0.03 m3/m3 typical in mineral soils that have solution electrical conductivity <8 dS/m
Medium specific calibration: ±0.01–0.02 m3/m3 in any porous medium
Apparent dielectric permittivity (εa): 1–40 (soil range) , ±1 εa (unitless) 40–80, 15% of measurement

| TEMPERATURE |
Range: −40 to 60 °C
Resolution: 0.1 °C
Accuracy: ±1 °C from −40 to 0 °C
±0.5 °C from 0 to +60 °C
NOTE: Temperature measurement, for applicable sensors, may not be accurate if sensor is not fully immersed in the medium of interest, due to longer equilibration time.
