The VFM200 is a VOC/formaldehyde meter that measures VOC (volatile organic compounds) and formaldehyde concentrations in real time. It features a fast response time, is compact and easy to transport, making it excellent for checking indoor air quality in homes, offices, factories, hotels, schools, and other indoor environments. Potential sources of VOCs include paints, finishes, adhesives, cigarette smoke, pesticides, personal care products, car exhaust, new furniture, wall coverings, household cleaners, and cooking fuels. Chemicals include acetone, ethylene glycol, formaldehyde, xylene, 1,3-butadiene, tetrachloroethene, hydrogen sulfide, ammonia, toluene, benzene, methylene chloride, perchloroethylene, and MTBE.
