Monitor air quality, CO2 concentration, formaldehyde, volatile organic substances. Temperature and humidity indicator. Отзыв

Attention! The device begins to work correctly after the first, after unpacking, 2-3 hours of operation. This is due to the fact that a microclimate occurs near the sensors during long-term storage and transportation. It should take 2-3 hours for full ventilation and volatilization of plaque that occurs during storage. 5-in-1 multifunctional air quality monitor detects and measures CO2, HCHO (formaldehyde), TVOC, indoor temperature and humidity. Indispensable at home, office classroom, hotel, gym, greenhouse, warehouse, etc. With a sensitive sensor, it provides fast and accurate data transmission to the digital LCD color screen. Equipped with a built-in 1200 mAh battery. The air quality monitor-detector analyzes the parameters according to several criteria at once. Designed to be aware of possible unwanted contaminants in the air you breathe at home or in the office, as well as to be aware of the need to ventilate or turn on the filter / purification system. Excessive dustiness or the presence of undesirable impurities in the air can lead to poor health, allergic reactions, and decreased performance. Air quality monitors allows you to display a composite air quality index in the form of a colored bar. Functions: Color LCD screen displays: Carbon dioxide content CO2 - detects air convection, quickly and accurately determines the concentration of CO2 in a living environment. The HCHO content is the concentration of formaldehyde vapor in the air. These can be decay products of various chemicals, formaldehyde can be released from low-quality furniture, when chipboard is heated, etc. The content of TVOC is the concentration of volatile organic substances (VOC). VOCs can be released from household chemicals, repairs, process disturbances, temperature, humidity, and battery levels. Digital LCD color screen for easy and clear reading even in the dark. Current temperature and relative humidity. 4-color indicator and beep: 0-799PPM (green), 800-1199PPM (yellow), 1200-1599PPM (orange), 1600PPM and above (red). Power - Built-in 1200mAh lithium battery, with Type C USB interface for fast charging via power adapter, power bank, laptop. Simple but stylish appearance, desktop or wall mounting, goes well with different styles of houses. Compact and lightweight, easy to carry.
