at the installation location. As the internal battery
creates a parasitic heat during the charging period,
the measurement accuracy may be affected by up to
1
ºC.
In battery mode, this model has significantly shorter
battery life than models without CO
2
concentration
measurement. For this reason, the measurement of CO
2
concentration
does
not
occur
as
often
as
the measurement of other variables. By default, this is 2
minutes with the option of extending up to 10 minutes
(option available in the Vision software).
We recommend that calibration of the relative humidity
and temperature of this device in the laboratory be
carried out with sufficient air flow (at least 1 m/s),
but only after a thorough settling, which may take up to
4 hours.
Due to low IP20 protection, this device is not suitable
for dusty or water-borne areas.
AR005348
Compact CO
2
concentration meter
This model is designed to measure
concentration
of CO2 in the air by internal sensors. No
additional
probes or sensors can be connected. It is characterized
by a simple and compact design and a relatively long
response in the measured quantities, compare to model
with external probes. The sensor is located under
the grid on the front and side of the unit. The device
is placed directly in the measured space, while
the installation needs to ensure sufficient level of GSM
signal at the installation location.
In battery mode,
this model has significantly shorter battery life than
models without CO2 concentration measurement.
The measurement of CO2 concentration occurs
2 minutes standardly with the option of extending up to
10 minutes (option is available in the Vision software).
Due to low IP20 protection, this device is not suitable
for dusty or water-borne areas.
