The UNOnext/UNOlite Indoor Air Quality Monitor can continuously monitor real-time data for seven types of harmful indoor air factors. The detection range includes Carbon Monoxide (CO), Carbon Dioxide (CO2), Fine Suspended Particulates (PM2.5), and Suspended Particulates ( PM10), Formaldehyde (HCHO), Ozone (O3), Total Volatile Organic Compounds (TVOC) and Temperature, Humidity, Illuminance, etc. UNOnext/UNOlite not only has a detection function, but it can also independently link ventilation equipment or integrate with central air conditioning. When indoor air quality turns poor, UNOnext/UNOlite immediately sets off an alarm and introduces fresh air to eliminate the bad indoor air. The innovative design of UNOnext/UNOlite also earns extra points for LEED green building standards and WELL healthy building standards.
