How We Can Help You
Agricultural Research and Networks
Soil water content (SWC), soil water potential (SWP), temperature, and electrical conductivity measurements give researchers, land managers, hydrologists, engineers, and others the insights they need to make confident soil management decisions.
Irrigation Scheduling and Management
Together, SWC and SWP give the most complete picture of plant‑available water. Automate measurements to support scheduling decisions that prevent over- or under-watering.
Environmental and Ecological Research
Our best-in-class time domain reflectometry (TDR) and complex dielectric through intersection (CDX) soil sensors set the standard for research objectives.
Watershed and Water Resource Studies
Whether your soil is droughted, flooded, or somewhere in between, Campbell Scientific sensors monitor soil moisture at depth and quantify recharge across complex terrain. Seamlessly scale from individual monitoring points to multi-site networks with centralized data management.
Featured Products
SoilVue™10 TDR Soil Moisture and Temperature Profile Sensor
Reduce installation time and soil disturbances with the SoilVue 10. This innovative TDR soil sensor provides excellent soil contact and enables soil moisture, electrical conductivity, and temperature profiles at six or nine depths, depending on the selected option.
TempVue™50 SDI-12 Digital Water Temperature Sensor
This rugged, reliable soil and water temperature sensor offers an SDI-12 output and advanced stability in nearly all monitoring conditions.
CS655 12 cm Soil Moisture and Temperature Sensor
This versatile sensor measures volumetric water content (VWC), bulk electrical conductivity, and temperature using two 12 cm stainless-steel rods.
CS650 30 cm Soil Moisture and Temperature Sensor
Similar to the CS655, the CS650 monitors VWC, bulk electrical conductivity, and temperature. The CS650 uses two 30 cm stainless-steel rods.
HS2 and HS2P Handheld Soil-Water Probes
The HS2 and HS2P are portable, handheld soil-water probes. The HS2P includes an insertion pole for easier use.
229 Heat Dissipation Matric Potential Sensor
Requiring no maintenance and unimpacted by salts in soil, the 229 reliably monitors SWP and is ideal for long-term installations.
Measurement Fundamentals
Soil Water Content Versus Soil Water Potential: Why Both Matter
Soil Water Content (SWC) tells you how much water is present in a volume of soil. Soil Water Potential (SWP) tells you the energy state of water in the soil, which provides insights into water movement in soil profiles that drive water processes.
A soil sample at field capacity and droughted soil may only differ modestly in water content but differ dramatically in water potential. SWC and SWP are related, but distinct measurements. In many applications, you need both measurements for a comprehensive understanding of soil condition.
