A dedicated CO2 data logger is a
recent addition to Gemini Data
Loggers Tinytag range.

The CO2 logger is suited to indoor
building monitoring, playing a key
role in helping to verify that
ventilation systems are
performing correctly.

There is a growing
awareness of the
need to monitor
carbon dioxide
levels within
buildings to help
maintain optimum
internal air quality: areas with
poor ventilation can lead to a buildup
in CO2 levels, which can cause
reduced concentration levels in
occupants and in some cases can
lead to health problems.

The discreet mains powered unit
uses a self-calibrating infrared sensor
to determine carbon dioxide
concentrations. A flashing red LED
indicates if there has been an
interruption to the power supply,
and the LED will also be triggered if
a user-defined upper ppm level limit
is reached.
