The new EXO-Skin Dynagage is based on tried and proven energy balance technology for sap flow measurement. The Dynagage has been the world leader in sensor shipments since 1990. Thousands of sensors have been fielded for research in agriculture, plant physiology, water relations, crop science and numerous ecological, hydrology and engineering studies. With the advent of sap flow monitoring in commercial vineyard applications, and the introduction of Low– Cost Sap flow systems, the Flow4 and Probe12, our customers needed an easier plant connection and a more economical sensor. Customers explained their needs for innovation and we designed the EXO-Skin sensor to solve some of the recurring issues with the well-respected Dynagage, the one piece integrated sap flow sensor.
