Psychrometer Accessories
ICT International offer a range of accessories:
- The PSY-IK Psychrometer Installation Kit provides the necessary components for the installation of both PSY1-Stem Psychrometer and PSY1-Leaf Psychrometer.Please note: the PSY-IK Psychrometer Installation Kit does not include the Stem Clamps and the Leaf Clamp, that have to be ordered separately.
- The Psychrometer clamps and osmotic potential insulator (OPI) are recommended accessories to secure the chamber in place during the installation. The clamps ensures that the chamber remains intact to a plant stem or leaf, while the OPI houses the chamber to provide a thermally insulated boundary.
Psychrometer Installation kit
The contents of the PSY-IK have been specified to ensure consistent installation of PSY1 Psychrometers. The contents align with the steps described in the User Manual.
Provided in a toolbox for easy transport, and to ensure all parts are kept together for repeat installations and general maintenance. Details are found under the Description Tab.
Psychrometer Clamps
The Psychrometer clamps are designed to hold the chamber securely in place against the xlyem. Available for stem or leaf chambers the clamps are available in different sizes:
- PSY1-Stem Psychrometer Clamps
The parts of the psychrometer clamping device includes the 1 frame, 2 hex screws, 1 moveable jaw attached to the jaw screw. The psychrometer chamber is attached to the frame using the hex screws. The gap between the chamber and moveable jaw can be adjusted according to the stem diameter. They are available in three (3) different sizes: small, medium and large.- Small stem psychrometer (PSYS-C37) – for stem sizes between 10 and 37 mm in diameter
- Medium stem psychrometer (PSYS-C77) – for stem sizes between 30 and 77 mm in diameter
- Large Stem Clamp (PSYS-C125) – for stem sizes between 78 and 125mm in diameter
- PSY1-Leaf Psychrometer Clamps
Leaf clamps come in 2 sizes with unique part numbers.
PSY1 Osmotic Potential Insulator (PSY-OPI)
The stem psychrometer chamber can also be used in determining the osmotic potential of plant materials such as leaves and stem. The Osmotic Potential Insulator (PSY-OPI) provides a thermally insulated boundary around the chamber.
In effect, this eliminates the introduction of thermal gradients caused by a need to handle the chamber to load samples and provides a stable insulated thermal buffer from ambient temperature gradients within the surrounding environment. Removing these factors enables a very rapid equilibration time between samples and high accuracy of measurement from -0.1 MPa to -10 MPa.
