the measurand into a standard signal of 0 -10 V or 4...20 mA (switchable).
Use just one device to monitor and control the entire indoor climate effectively. This enables energy-saving room ventilation on an as-needed basis,
thereby reducing operating costs and improving well-being. It is used in offices, hotels, convention centres, apartments, shops, etc. We recommend
one sensor for every 30 m² of space.
A long-term stable, digital humidity and temperature sensor guarantees exact measurement results. The CO2 content of the air is measured using
an optical NDIR sensor (non-dispersive infra-red technology). An optical particulate sensor precisely detects fine dust (PM) of the size category 0.3
to 10 micrometers. The sensor is factory-calibrated; an environmental precision adjustment by an expert is possible. (except for particulate sensor)
