To use the buffer bottle, make sure
that the tubing is clear from
obstruction. Connect the In tubing to
the unit. Place the buffer bottle in a
location that has stable CO
2
concentration (away from operator,
cars, furnace, photosynthesizing
plants). Here, ambient air CO
2
levels
should be approximately 400 ppm.
Note: The instrument shown in these images is a CI-340 Photosynthesis Analyzer. The buffer tank
system technique can be used to help stabilize the ambient intake of any IRGA
CO
2
sensor (images
