Authentical Granier Sap Flow Sensors

Authentic Granier’s original design (Granier (1985, 1987) & Lu et al (2004)), the PlantSensors probes can be directly hooked up to a generic data logger.

Standard Granier (TDP) sap flow sensor is PS-GP3.5×2: 3.5 cm long with its distal 2 cm as effective sensing part.

PlantSensors also supply sensors of special length for sap flux density depth profile study as below:

PS-GP2.5×1:    2.5 cm long probe with 1 cm long sensing part;
PS-GP5x2:       5 cm long probe with 2 cm long sensing part;
PS-GP10x2:    10 cm long probe with 2 cm long sensing part.

This range of sensors can cover the sapwood depth from 1-10cm.
