Our Pressure Plate Cells have been the de-facto standard for the measurement of soil moisture retention studies worldwide. The development of these ceramic cells by Soilmoisture in the 1950’s led to the now universally accepted method for measurement of multiple soil samples extracted on a single reusable ceramic plate. Researcher’s dedication to our Soilmoisture cells is understandable. Each cell is carefully hand fabricated from our fine porous ceramic plate materials and covered with a heavy duty neoprene skirting that provides for water holding capabilities used in our pressure cell extractors Model 1500 & 1600.
