11. e After the warm up period the sensor interprets the currently read VOC value as zero point independently from the actual concentration An internal algorithm continuously updates the zero point by taking the lowest measured VOC value Therefore the ambient air should be of low VOC content after the warm up period This can be obtained by shortly venting when starting the measurements with the 80 signal If the sensor isn t started at low VOC concentrations it can take a couple of days until the internal algorithm has updated the zero point so far that effective measuring results are available The natural sensor drift and ageing is corrected by the implemented control algorithms Indoor Air Typical Substances Ventilation ee Emission Source VOCs Others ource Acetone Ethanol Isoprene Breath CO2 Humidity Skin respiration amp Nonanal Decanal a Pinene transpiration Humidity demand Flatus Methane Hydrogen controlled Human Being A Cosmetics Limonene Eucalyptol Household Supplies Alcohols Esters Limonene Combustion Unburnt Hydrocarbons Engines CO Appliances Tobacco CO2 Smoke Humidity Paints Formaldehyde Alkanes ai Adhesives Building Material Solvent Alcohols Aldehydes x i olvents Ket Sil permanent Furniture Carpets etones olloxanes 5 10 Office Equipment ye E E E Consumer Products Goa SOME A il eae Printers Copiers Benze
