Water Potential 401–Advances in Field Water Potential


In this webinar, Dr. Doug Cobos discusses field water potential sensor characteristics, equilibrations and advances in technology. 

In this webinar, Dr. Doug Cobos discusses the importance of water potential and field water potential sensor characteristics including measurement range, accuracy, and other considerations. He compares different types of sensor equilibrations such as liquid, vapor, and porous matrix. He also discusses recent advances in water potential technology.

Next steps


Our scientists have decades of experience helping researchers and growers measure the soil-plant-atmosphere continuum. 



Dr. Cobos is a Research Scientist and the Director of Research and Development at METER.  He also holds an adjunct appointment in the Department of Crop and Soil Sciences at Washington State University where he co-teaches Environmental Biophysics.  Doug’s Masters Degree from Texas A&M and Ph.D. from the University of Minnesota focused on field-scale fluxes of CO2 and mercury, respectively.  Doug was hired at METER to be the Lead Engineer in charge of designing the Thermal and Electrical Conductivity Probe (TECP) that flew to Mars aboard NASA’s 2008 Phoenix Scout Lander.  His current research is centered on instrumentation development for soil and plant sciences.
