Field Mode
To use the F-900 Field Kit in the field or laboratory, attach the hoses of the chamber wand to the IN
and OUT ports on the front panel. Slide the end of the wand into the chamber and tighten the
thumb-screw. Make sure the connection is snug. The fans inside the chamber will begin to spin
when the connection is established. The chambers available with the field kit are 2L or 4L. The
chamber has a slit to allow for non-destructive sampling. A fruit that is still connected to the plant
can be passed through the slit and then closed in the chamber. This allows ethylene levels to be
recorded during ripening without damaging the fruit. Leaf chambers available for the CI-340
Photosynthesis System are compatible and interchangeable with the F-900 Field Kit.
To sample a fruit:
Open a data file to save the measurements to.
Attach the chamber to the F-900 by screwing on the wand to the top of the chamber.
Next, connect the IN/OUT gas tubing to the ports on the front of the F-900.
Connect the black power chamber cable to the left of the display.
Place the fruit inside the chamber and close it.
Observe and record the rate of change of ethylene over time with the F-900 Monitor Mode.

and gas IN and OUT on the F-900 front panel (right).
If the tube is removed from the OUT port, ambient air will be used to replenish the fruit chamber.
