Measurement with control unit + CO
To avoid the effects of the CO2 content of respired air, hold
the probe as far away from your body as possible.
The measured CO2 value depends on the absolute
atmospheric pressure. This effect is compensated by the
device internally. For this, enter the absolute pressure of
the location in the main menu. The displayed CO2 value
is automatically compensated to the entered absolute
pressure.
The measuring principle is based on infrared absorption.
This type of probe has a relatively high power
consumption. For long-term measurements, use the
mains adapter and rechargeable batteries.
If sudden changes occur in the concentration, the probe
will require 30 – 60 sec. to adapt to the environment.
Gently waving the probe reduces the adaptation time.
The probe 0632.1240 measures concentrations of 0...9999
ppm.
