Sap Flow Sensor

The Implexx Sap Flow Sensor to monitor sap flow, transpiration and the stem water content in plants. An advanced but easy to use sap flow sensor designed by scientists that uses a thermometric sensor based on the heat pulse family of method. This sensor integrates with the vanwaltDataHub for the remote collection of plant data.
