CO
2
Gassing
As fourth module, the CO
2
Gassing allows
examination of the short- and long-term
effects of the so-called “CO
2
manuring
effect” on plants of the categories C3 or
C4. The CO
2
sensor is equipped with a
multi-position CO
2
and temperature adjust-
ment, which is a guarantee for outstanding
measurement accuracy. Due to the NDIR
two-beam method the sensor is insensitive
to soiling, and ageing effects are compen-
sated automatically. Furthermore, the CO
2
sensor has an excellent long-term stability
and auto-calibration. The CO
2
concentra-
tion is controlled by the CONTROL2015
touch
, the documentation of the measured
concentration is effected by the integrated
recorder. This option ensures successful
plant growth tests.
The CO
2
Gassing is only available in the
Premium-Line.
Application ranges of the CO
2
Gassing:
Plant research
Zoology and botany, such as for
measurement of the effects on the
CO
2
rise in the atmosphere
Tests with “CO
2
manuring”: The growth of some
plant species is by up to 40 percent quicker.
The CO
2
Gassing –
stimulation of the photosynthesis
RUMED
®
Test and Simulation Equipment can be equipped with the
option CO
2
Gassing to test the direct effects of increase of the CO
2
concentration on plants with simultaneous temperature, humidity
and light control.
