Overview PRECISION MONITORING. Real time, advanced sensors for measuring PM2.5/PM10 (fine particulates, smog, smoke), Carbon Dioxide (CO2), and Formaldehyde (HCHO), temperature and humidity simultaneously. One specialized sensor for each air pollutant. PORTABLE. Rechargeable battery. Ready to use in home (any room), car, office, hotel even camping/hiking. MULTI-FUNCTIONAL. Several screen options that show real time measurements. Also tracks and graphs historical data for up to and an hour. Easy to use, switch between screens with the click of a button. DYNAMIC. Indicates when PM2.5, HCHO, CO2 levels are at harmful levels. Coloring of the digital reading and definition change, showing where the air quality falls on the international scale and how harmful it is at your location. Ranging from green to dark purple and excellent to severe respectively. Product Description This is a precision Air Quality Monitor than can be used in any room of the house, hotel, office, or car. You can even take it camping. Whether it be smoke from a forest fire 100s of miles away, smog during your daily commute, or chemicals commonly used in the production of many household items; AQM3.0 provides accurate air quality data to so you and your family know what’s in your air at all times. Air Monitoring What air pollutants am I measuring? PM2.5 – fine particulate matter including dust, smog, smoke Formaldehyde (HCHO) – a harmful chemical used in many building materials and common household products Carbon Dioxide (CO2) – naturally occurring but also caused by burning of fossil fuels.
