Ten 15 in 1 air quality testers integrate multiple measurement functions AQI, CO, CO2, PM0,3, PM1,0, PM2,5, PM10, formaldehyde, TVOC, temperature, humidity, as well as adjustable time, alarm, timer and timer - a ready-made solution for your air quality needs. Support alarm limits, sleep mode settings and no detailed data on air parameters for a given day, month or year. Multifunctional design, support do devices temperature control, time settings and alarm switch. It provides a comprehensive way to monitor the air quality in your home, so you can stay up-to-date on the air condition in your home, wherever you are, and at any time. Characteristics: Comprehensive air quality test: Ten functions of 15-function air quality tester integrate many tests of AQI, CO, CO2, PM0,3, PM1,0, PM2,5, PM10, formaldehyde, TVOC, temperature, humidity, as well as time display, alarm, timer and timer functions, an alternative solution that ensures air quality safety. TFT color display and application control: 2,8 inch TFT color screen, at a glance clearly visible test data. The application allows you to check whether it is possible or not and is controlled by an air management system anywhere. Personalized settings and historical data checking: Support for alarm limits, sleep mode setting and uncontrolled exploration of detailed historical data on air parameters by day, month or year. The app also has a user interface with an app that includes temperature units and extended timer settings that are available and convenient to use to meet your needs. Warning and alert: When connected to a Wi-Fi network, you can set the alarm value according to your needs. When the measured data exceeds the norm, the device immediately triggers three alarms, sound signals, the color of the interface changes depending on the air quality (green - nice, orange - warning, red - bad), eliminating repair errors. Intelligent connection control: equipped with top-class sensors and lasers that take measurements into account. It can be equipped with a smart plug to control access. You can connect an exhaust fan that will turn off when the CO2 concentration exceeds 1500 ppm and turn off when it falls below 800 ppm, thus saving electricity. Applicable to families, schools, hospitals, children's rooms, hotels, restaurants, cars and other places.
