We will be happy to answer any questions you may have about indoor air or the air-Q. We are also open to sales partnerships and collaborations and look forward to hearing from you.
The VOC sensor in the air-Q is very flexible and can detect a wide range of VOCs. These include formaldehydebenzene, toluene, xylene, acetone, styrene, terpenes, trichloroethylene, tetrachloroethylene, naphthalene, ethyl acetate, methanol, chloroform, cyclohexane or 1,3-butadiene as well as hundreds of other VOCs. We have written a fascinating blog article on the origins and sources of these substances.
Unfortunately, VOC sensors in general, including the VOC sensor in the air-Q, output the VOC measured value as a total value. This means that the substances mentioned above can be measured but not output individually. If these or other VOCs are in the air, the VOC measured value will increase. However, it remains unclear which chemical is the driver of the measured value.
The VOC PID sensor offered for the air-Q Science can be set to a substance so that the exact quantity can be quantified very well. Attention: The VOC PID sensor is only suitable for professional applications in laboratories or industry.
Yes, the measurement data is stored on an SD card in the device. Depending on the product variant, it is 16 GB in size. With a data volume of 1.5 MB per day and all planned additional functions and data, the storage space is sufficient for well over 10 years.
Question asked by: Horst R.
The Health Index is based on the limit values of the Federal Environment Agency, the WHO and the so-called Vienna Health Index. The air-Q health index is always calculated from the "worst" measured value from all measured variables at a certain point in time. If, for example, the increased particulate matter value leads to a 20% discount and the high nitrogen dioxide value justifies a 30% health discount, the health index shows 100% - 30% (nitrogen dioxide value) = 70%.
The calculation of the performance index is based on a different, cumulative procedure, which is based on recent studies by various research institutions that have analyzed the performance degradation of certain loads in the breathing air. For example, if the high carbon dioxide content of the air leads to a 20% performance penalty and the high temperature leads to a 5% penalty, the performance index shows 100% - 20% (CO₂ penalty) - 5% (temperature penalty) = 75%.
