• The air quality tester has a built-in professional detection sensor that can accurately track air quality, including HCHO (formaldehyde), CO2, PM2.5, PM1.0 and PM10 (particulate matter), TVOC (total volatile organic compounds), AQI,temperature and humidity.

• Portable carbon dioxide detector: portable detector, palm-sized, easy to carry, can detect the gas quality in the bedroom, living room, kitchen, office, school, hotel, campground and other environments. These data can indirectly understand the existence of second-hand smoke and mold, which can issue health warnings.

• Durable 3000 mAh battery: The built-in 3000 mAh battery can provide up to 3-5 hours of use when fully charged. It can also provide real-time power through the included USB charging cable, so you can wear it on your bedside table or desk as a clock without worrying about running out of battery.

• Simple operation and customer service: You can open/close and switch screen information with one-key operation, and a detailed instruction manual is attached. If you have any questions about our products and services, please feel free to contact us.

• Accurate & Fast Detection： Adopts high precision chips,1 second update and instant response after starting up. Our air quality detector is designed to be used simply requires no calibration
