AIR8 Guard Pro air quality meter

This air quality meter is a CO2 meter, a particulate meter and a harmful gas detector all in one! It measures the CO2 content, which is the best indicator of whether a room is sufficiently ventilated, as well as the content of fine dust and volatile organic compounds that indicate whether there is an excess of toxic substances. The AIR8 Guard Pro also determines the content of the carcinogenic formaldehyde (HCHO).

The Air Quality Index (AQI) colour and smiley indicator shows at a glance whether action is required.

This multifunctional air quality meter keeps a finger on the pulse when it comes to a healthy working and living environment. The CO2 sensor indicates whether a room is sufficiently ventilated. The fine dust sensor signals whether there are any responsible levels of fine particles in the air, and the TVOC sensor monitors the presence of unhealthy organic substances.

Extra special is that the AIR8 Guard Pro detects formaldehyde (HCHO). This is a toxic gas that can be released from building and insulation materials and textiles, among other things. Tobacco smoke also contains the carcinogenic formaldehyde.
