Product Line

Measurements Made Water Content Accuracy Required Equipment Soil Suitability Rods Sensors

SoilVue 10

Volumetric water content (VWC), permittivity, electrical conductivity (EC), and temperature 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.

CS655

Soil electrical conductivity (EC), relative dielectric permittivity, volumetric water content (VWC), soil temperature
  • 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
Measurement system Short rods are easy to install in hard soil. Suitable for soils with higher electrical conductivity. Not replaceable Not interchangeable

Measurements Made Water Content Accuracy Required Equipment Soil Suitability Rods Sensors

CS650

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

CS616

Volumetric water content (VWC) of porous media (such as soil) ±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) Measurement system Long rods and lower frequency are well-suited for soft soil with low electrical conductivity (< 2 dS/m). Not replaceable Not interchangeable

HS2

Volumetric water content (VWC) of porous media (such as soil)
  • 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.)
HS2 is a complete system. Short rods are easy to install in hard soil. Suitable for soils with higher electrical conductivity. Replaceable Interchangeable sensors; can swap the 12 cm and 20 cm sensors with the reader.

HS2P

Volumetric water content (VWC) of porous media (such as soil)
  • Probe Options: 3% typical (Accuracy assumes solution EC of < 4 dS/m when using the CS658P 20-cm probe.)
  • Probe Options: 3% typical (Accuracy assumes solution EC of < 6.5 dS/m when using the CS659P 12-cm probe.)
HS2P is a complete system. Short rods are easy to install in hard soil. Suitable for soils with higher electrical conductivity. Replaceable Interchangeable sensors; can swap the 12 cm and 20 cm sensors with the reader.
