Dr. Colin Campbell compares measurement theory, the pros and cons of each method, and why modern sensing is about more than just the sensor. Choosing a water content sensor from the many sensor types available may leave you feeling confused and overwhelmed. Every measurement method has strengths and limitations, but which method is right for you?

In this webinar, Dr. Colin Campbell demystifies the differences between soil water content measurement methods. He explores the scientific measurement theory and the pros and cons of each method. He also explains which technology might apply to different types of field research, and why modern sensing is about more than just the sensor.

Join Dr. Colin Campbell as he discusses:
- Measurement theory behind the gravimetric method, capacitance, time-domain reflectometry (TDR), time-domain transmission (TDT), frequency-domain reflectometry (FDR), resistance sensors, and more
- Which technology applies to different field situations
- What factors matter when choosing a sensor type
- Why some methods are not research-grade
- How modern sensing is about more than just the sensor
- How to determine a good price-to-performance ratio for your unique application

Presenter:
Dr. Colin Campbell has been a research scientist at METER for 20 years following his Ph.D. at Texas A&M University in Soil Physics. He is currently serving as President of METER Group. He is also adjunct faculty with the Dept. of Crop and Soil Sciences at Washington State University where he co-teaches Environmental Biophysics, a class he took over from his father, Gaylon, nearly 20 years ago. Dr. Campbell’s early research focused on field-scale measurements of CO2 and water vapor flux but has shifted toward moisture and heat flow instrumentation for the soil-plant-atmosphere continuum.
