Overview

The SoilVUE™10 is a soil water content profile sensor powered by Campbell TrueWave™TDR technology. This soil moisture, electrical conductivity, and temperature profile sensor was developed with environmental researchers and environmental monitoring networks in mind. The SoilVUE™10 represents several exciting advancements in in-situ soil measurement that should make this an extremely compelling option for anyone in these applications who needs to make multiple measurements in a profile. 

Campbell Scientific’s proprietary TrueWave™TDR technology combines a best-in-class rise time with an advanced waveform analysis technique to determine the true travel time of a high-frequency pulse. This process achieves a high-resolution, smooth signal for measurements that are defensible and can be universally compared with other TDR measurements. Not all TDR-based sensors perform equally well.

1 m Option 5, 10, 20, 30, 40, 50, 60, 75, and 100 cm (2, 4, 8, 12, 16, 20, 24, 30, and 40 in.)

Electrical Conductivity

Range 0 to 10 dS/m
Accuracy
  • ±2% (0 to 2.5 dS/m)
  • ±5% (full range)

Relative Dielectric Permittivity

Range 1 to 80

Volumetric Water Content

Water Content Accuracy ±1.5% typical with most soils

Soils with high organic matter (> 12% soil organic carbon) or high clay content (> 45% clay) may need a soil-specific calibration due to the dispersive nature of these materials.

Soil Temperature

Accuracy ± 0.15°C (between -30° and +40°C)
