For permanent measurement, the air quality monitor can be connected to the mains via a USB interface. The rechargeable battery will be recharged within two hours if the air quality monitor is turned off. The display of the concentrations is further simplified by the use of a color rating scale, as this directly provides information about the air quality to the user.
In addition to the indicative measurement of formaldehyde, which can be harmful to health, there is also an orienting measurement of particulate matter pollution to be carried out. A distinction is made between particles with a maximum diameter of up to 10 μm (PM10) and particles up to a diameter of 2.5 μm (PM2.5).
