APPENDIX E
CANOPY CHAMBER ASSEMBLY INSTRUCTIONS
The Canopy Chamber Attachment is another feature of Closed System measurements. This
attachment is designed to be used with the canopy chamber enclosures measuring canopy
photosynthesis. The enclosures could be of varying sizes, all of which the user can determine.
The following conditions represent the kinds of enclosures that are acceptable:
•
Materials that are not light-reflected, gas-permeable, light-impenetrable (such as plastic
bags, acrylic shells, most glass canopies)
•
Larger than the manufacturer’s LC
-10 chamber (4-liter volume)
•
Larger than the measuring sample environment
For accurate installation of this attachment (see Figure E-1), the chamber enclosure must
accommodate for an (circular) opening (approximately 65 mm (2-
1/2”)) on one of the sides. An
additional slot can be made for the PAR sensor on the enclosure for accurate measurements of
ambient light intensity. Canopy Chamber Attachment ‘A’ has a pos
ition for the PAR sensor
placement; however, this position will not always provide reliable measurements of ambient
light intensity.
To prepare for measurements, align Attachment ‘A’ and Attachment ‘B’ with the seals facing the
enclosure. With this alignm
ent, the tubes (in Attachment ‘A’) should slide into the respective
holes in Attachment ‘B’. Secure the entire Canopy Chamber Attachment onto the enclosure by
tightening the thumbscrews from Attachment ‘B’.
NOTE: When using the IR Temperature sensor, be sure that the 65mm diameter opening is
clear of any obstruction from within the enclosure. This is to ensure accurate leaf
temperature measurements.
Now, attach the Canopy Chamber Attachment to the CI-340 by gently sliding the exposed tubes
into the holes and tightening the locking screw of the CI-340. Place the IR Temperature sensor
firmly into the opening located on Attachment ‘A’. Plug the IR Temperature sensor connector
into its CI-
340 port. Finally, insert the PAR sensor into the slot of Attachment ‘A’
or in the
enclosure opening. If the chamber enclosure is made of flexible material, a tripod is suggested
for an appropriate support of the CI-340.
Plant Canopy Chamber Accessory
Plant canopy chamber measurements have a unique advantage because variation within
individual leaf measurements is minimized and an accurate picture of whole plant photosynthesis can
be seen. These differences are caused by the heterogeneous distribution of leaves within the plant
canopy, due to uneven distribution of radiation, humidity and heat.
