System Introduction:

French Academy of Agricultural Sciences(INRA)ofGranierProfessor in1985Invented in the yearGranierThermal dissipation probe method（thermal dissipation probe）The trunk sap flow measurement system is now widely used in the study of plant physiology and ecology. applicationGranierThe method of using a heat dissipation probe to measure the sap flow of woody plant trunks can quantitatively measure the transpiration rate of the entire tree.

Aoda Plant Sensing Instrument Company(PlantSensors, Australian Enterprise Number-ABN)1994selfSince the beginning of the year, we have specialized in producing authentic original modelsGranierHeat dissipation probe and provide a complete setGranier

Trunk sap flow measurement system.The authentic original model we produceGranierThe heat dissipation probe fully complies withGranier(1985)Calibration parameters. Our customers include the United States(Including the US Department of Energy's Oak Ridge National LaboratoryORNL), UK(Including the Royal College of LondonIC), Australia(Including the Federal Organization for Science and TechnologyCSIROThe University of QueenslandUQ), France(Including the Academy of Agricultural SciencesINRAThe National Research CenterCNRSThe International Center for Agricultural Research and DevelopmentCIRAD)

Research institutions and universities in South Africa, Israel, Greece, Singapore, and China. The research results obtained using our produced probes and systems have been published in many international core journals.2004Dr. Ping Lu, Senior Research Scientist at the Commonwealth Scientific and Industrial Organization of AustraliaAnnual publications related toGranier
