The service life of individual sensors installed in the air-Q air measuring device is - depending on the measuring principles - sometimes infinitely long:
- particulates sensor measures the particles optically. No wear and tear.
- Carbon monoxide sensor measures according to a chemical principle. Service life > ten years
- Carbon dioxide sensor > ten years
- Sulphur dioxide sensor > seven years
- Ozone sensor > five years
- Oxygen sensor measures according to the principle of optical luminescence. Service life > 5 years
- Nitrogen dioxide sensor measures electrochemically. Service life > 5 years
- VOC sensor > ten years
