SoilVUE10

Volumetric Water Content: ±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.
Volumetric water content (VWC), permittivity, electrical conductivity (EC), and temperature

CS655

  • Volumetric Water Content: ±1% (with soil-specific calibration) where solution EC < 3 dS/m
  • Volumetric Water Content: ±3% (typical with factory VWC model) where solution EC < 10 dS/m
Short rods are easy to install in hard soil. Suitable for soils with higher electrical conductivity. Measurement system Soil electrical conductivity (EC), relative dielectric permittivity, volumetric water content (VWC), soil temperature Not interchangeable Not replaceable

CS650

  • Volumetric Water Content: ±1% (with soil-specific calibration)
  • Volumetric Water Content: ±3% (typical with factory VWC model) where solution EC < 3 dS/m
Long rods with large sensing volume (> 6 L) are suitable for soils with low to moderate electrical conductivity. Measurement system Soil electrical conductivity (EC), relative dielectric permittivity, volumetric water content (VWC), soil temperature Not interchangeable Not replaceable

CS616

±2.5% VWC (using standard calibration with bulk EC of ≤ 0.5 dS m-1, bulk density of ≤ 1.55 g cm-3, and measurement range of 0% to 50% VWC) Long rods and lower frequency are well-suited for soft soil with low electrical conductivity (< 2 dS/m). Measurement system Volumetric water content (VWC) of porous media (such as soil) Not interchangeable Not replaceable

HS2

  • Probe Options: 3% typical (Accuracy assumes solution EC of < 4 dS/m when using the CS658 20-cm probe.)
  • Probe Options: 3% typical (Accuracy assumes solution EC of < 6.5 dS/m when using the CS659 12-cm probe.)
Short rods are easy to install in hard soil. Suitable for soils with higher electrical conductivity. HS2 is a complete system. Volumetric water content (VWC) of porous media (such as soil) Interchangeable sensors; can swap the 12 cm and 20 cm sensors with the reader. Replaceable
