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, and engineers 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.

Rugged, reliable soil and water temperature sensor offering an SDI-12 output and advanced stability in nearly all monitoring conditions.
CS655 12 cm Soil Moisture and Temperature Sensor
Versatile sensor measuring volumetric water content (VWC), bulk electrical conductivity, and temperature using two 12 cm stainless-steel rods.
CS650 30 cm Soil Moisture and Temperature Sensor
Monitors VWC, bulk electrical conductivity, and temperature using two 30 cm stainless-steel rods. Ideal for deeper profile measurements.
HS2 and HS2P Handheld Soil Moisture Sensors
Portable, handheld soil-water probes. The HS2P includes an insertion pole for easier use.
229 Heat Dissipation Matric Potential Sensor
Requires no maintenance and is unimpacted by salts in soil. Reliably monitors soil water potential (SWP) and is ideal for long-term installations.
Measurement Fundamentals
Soil Water Content vs. 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.
