It all began over 50 years ago when our founder, P.E. Skaling, joined the staff of the U.S. Salinity Laboratory in Riverside, California. While there, he participated in soils/moisture research, and built the first Pressure Membrane Extractor and First Tensiometers (an instrument that is now accepted and used on a global basis).

The Pressure Membrane Extractor, and subsequent ceramic plate extractors, made it possible to characterize the moisture-holding capacities of soils. Our revolutionary tools radically transformed irrigation practices, allowing for the establishment of soil-moisture standards now used worldwide.

Every day, universities, colleges, government agencies, commercial agriculture and industry around the world rely on Soilmoisture agronomic equipment.

From our location in Santa Barbara, California's beautiful central coast, we have reputation of service and quality instrumentation that spans over a half a century of innovation.
