Air Quality Pollution Monitor, Formaldehyde Detector, Temperature & Humidity Meter, Sensor, Tester; Detect PM2.5/PM10/PM1.0 Micron Dust, Test Indoor TVOC Volatile Organic Compound Gas; eBook Air Quality Monitor w/ PM2.5, TVOC, HCHO, Temp/Humid (B078ZS8RVL) 110.37

Have you gone nose blind to household odors or dust? Check multiple measures of your home's air quality. This air quality monitor has a FAN onboard that allows REAL-TIME accurate monitoring of temperature (in C), humidity, formaldehyde (HCHO), total volatile organic compounds (TVOC), and micron-sized fine particulate dust (PM2.5/PM1.0/PM10). Formaldehyde is an environmental carcinogen yet odorless at lower concentrations. Detect low levels of airborne TVOCs not perceivable to the human nose. Problems with allergies? See when you need to change your home’s air filter. Watch the levels of indoor total volatile organic compounds and formaldehyde drop when the windows are opened. Learn where air quality is poorer and where your allergies can worsen. Allergies that are difficult to control with unexplained coughing, runny nose, and shortness of breath may be signs of sick building syndrome. Tips on Use: -Calibrate on first use, esp. if 0.000 indoor readings noted. -If the HCHO, temp, or PM2.5 is inaccurate, use the "Sensor Set" Menu found under SET (press D), then SENSOR (press A) to further calibrate device readings. -Large variations & 9.999 TVOC readings do not indicate an error as this instrument is a sensitive electronic nose; environmental TVOCs vary much and high TVOCs often can result from interference from benign fragrances or odors.
