Air Quality Monitor Formaldehyde Detector Pollution Meter Sensor er Detect & Indoor Pollution New HouseFeatures: Using ARM s most of the wod's samrtphone processors are produced by ARM with 32-bit high-speed processing performance which greatly increases the computing speedmore accurate detection and smooth. The hazard degree of harmful gases such as formaldehyde and TVOC isn't a static tracking in order to systematically grasp the health of the Environment.The Air Quality er is widely used in homes offices enterprises governments schools etc.The Air Quality Formaldehyde Detector with built-in electric chemical sensors can accurately detect carbon dioxide (CO2) formaldehyde (HCHO) volatile organic compounds (TVOC) and particulate matter (PM2.5/PM10) in the air. These readings involve the detection of toluene harmful chemicals and pollutants in the air.Colored screen intelligent control stable quick you can get the precise figure easily.
