Directly measure 14 PS-GP sensors. can measure 6 more sensors than the PS-TDP8 system; need an extra PS-PS12 power supply unit.

Truly Granier`s original design (Granier 1985), the PlantSensors probes can be directly hooked up to a data logger.

We also provide the fully pre-wired complete Granier sap flow measuring system including logger, probes, cables, power supply units and solar panel etc.

Constant current power supply unit has several advantages over the commonly used unit with constant voltage (see Lu et al 2004). Each PS-PS12 unit can supply constant current to up to 12 PS-GP-30 sensors.
