Atmospheric pressures
Compared to other meteorological parameters, the atmospheric pressure sensors are not installed in the outdoor but in the same environmental system as the indoor and outdoor pressure is the same. The basic model DQA240 is installed in the same datalogger offering a low level output and a low electric consumption. The models DQA250 and DQA223 for wall mounting incorporate additional characteristics like thermal compensation or height correction (the atmospheric pressure decreases with the height).
