Equipment for characterizing quality of air in e.g. professional building, has sequencer controlling opening and closing of valves according to characterization cycle of corresponding characterization sensors
The equipment has characterization sensors (13a-13d) for characterizing a specific chemical component supplied from a sampling point (2) by an air distribution circuit (18). The distribution circuit comprises input for each of the sensors and bypasses (18a-18c) opening into sampling chambers, which accommodates the sensors. Each bypass comprises valves (11a-11c) for controlling a power supply of the corresponding sampling chambers. A sequencer controls opening and closing of the valves according to a characterization cycle of the corresponding sensors.
