The Sensor measures: Sap Flow
Cable Length: 5 meters
Power Supply: 12 V
Sensor for use in: Outdoor

The SF-L (SF-10) SAP Flow Sensor is an improved Granier sensor.
The improvements are:
Correction of measurement errors due to vertical temperature gradient of tree trunk: the vertical trunk temperature is measured separately and subtracted from the data of sap flow. In this way the sap flow is measured more accurately, and the zero-point of sap flow remains stable for a long time.
Continuous determination of water-saturation level of the tree body with a Dendrometer
New definition of zero sap flow: sap flow = 0 when the relative humidity in the crown => 100%, and the tree body is saturated with water (indicated by the dendrometer curve)  

Advantages:
Significant higher accuracy
Correct identification of zero sap flow
Correct Measurement of sap flow in night time
Additional data on tree growth measured by a dendrometer
Reusable sensor 

Disadvantages:
Not suitable for trees with diameters <15 cm
