CO
2
Control
(optional)
The 6400-01 CO
2
Injector System
consists of an electronic controller,
a CO
2
Source Assembly that uses
readily-available cartridges for portable
operation, and a CO
2
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
Injector System provides
a constant CO
2
input from 50 to
2000 μmol mol
-1
. CO
2
is controlled
by delivering a precisely controlled
pure CO
2
stream into air that is
CO
2
-free. The CO
2
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
2
concentrations and
easy generation of CO
2
response
curves. The CO
2
injector is under
complete software control, allowing
you to manually set CO
2
levels from
