PSY Logger Mounting and Sensor InstallationInstallation is an important aspect best explained by watching the SP03, SP04and SP05 installation videos.Care must be taken to prepare the site for installation:(a) Latex exudates seeping from the stem. It would not be acceptable toinstall the Psychrometer under these conditions.(b) A stem that has been prepared appropriately. The xylem under the latexsource is exposed. The Psychrometer can be successfully installed.Note: Any living tissue left behind will grow into the chamber and causedamage to the thermocouples.The stem psychrometer can be installed on woody, herbaceous and hollow(bamboo) stems of greater than 10mm diameter. With additional care,preparation and specific clamps, the stem psychrometer can also be used onfruits and leaves.When attaching the psychrometer it is important not to over tighten theclamping mechanism on softer plant issues to prevent damage to theinstallation site.Selecting a SiteStems with flattened portions are more conductive to efficient sealing. Insituations where it is not possible to easily or safely access appropriate smalldiameter branches (ie: branches of an appropriate size for the clamp used),the psychrometer can be installed on large diameter trunks or on leaves.
