Highly developed, technically sophisticated, according to laboratory standards - simply measure air.

The air-Q is the result of several years of research and development. Accordingly, it is technically mature and highly developed. In addition to the sensor components, a complex, software-based algorithm was developed that enables the detection of previously hidden particles in the air.

air-Q air quality meter technology

Our scientific approach to air analysis

Dr Daniel Lehmann - In the laboratory with the air-Q air measuring device

The technology of the air-Q has been developed since 2015 together with several scientific partners according to laboratory standards. The aim of the research was to develop an indoor air measuring device - the air analyser - with smart technology that measures air quality according to the most modern standards, but is compact and affordable at the same time. This meets the needs of both professional and private users who want to know more about the air they breathe.

To achieve the goals, individual sensor components have been completely redeveloped. Furthermore, there is the demand to make the measured parameters and values available in a way that is as easy to understand and transparent as possible. Software algorithms are even used to detect situations in the air that could previously only be clarified by laboratory tests. This makes the air-Q the most comprehensive, powerful and intelligent analyser of air and air quality - "Made in Germany".
