CO
2
Control (optional)
The 6400-01 CO
Injector System
consists of an electronic controller,
a CO
2
2
Source Assembly that uses
readily-available cartridges for portable
operation, and a CO
tank fitting for
greenhouse or laboratory operation.
All parts integrate directly into the
standard console with no external
batteries or control modules.
The CO
2
2
Injector System provides
a constant CO
input from 50 to
2000 µmol mol
2
-1
. CO
is controlled
by delivering a precisely controlled
pure CO
2
2
stream into air that is
CO
2
-free. The CO
concentration can
be controlled at the incoming air
stream or at the leaf surface to within
1 ppm of a target value.

The 6400-01 facilitates measurements
at elevated CO
concentrations and
easy generation of CO
2
response
curves. The CO
2
2
injector is under
complete software control, allowing
you to manually set CO
levels from the console, or use AutoPrograms to make measurements
at a series of concentrations.
12g cartridges provide up to 8 hours of operation.
The
cartridges
are
accessible outside the
instrument,
making them easy to change.
