Q1: What air quality monitor?
A1: Air quality monitor is a product that can detect formaldehyde, PM2.5, TVOC and temperature and humidity in real-time, small and exquisite, easy to carry. Through its internal original imported sensor, it can accurately measure the pollutant concentration and calculate the air quality index AQI, and alarm when the concentration exceeds the standard.
Q2: How does an air quality monitor work?
A2: Air quality monitors are equipped with several sensors to detect different types of pollutants. Electrochemical sensors detect oxygen levels and the presence of toxic gases by reducing oxygen through electrodes and measuring its concentration. Particle detectors detect dust, pollen and mold by passing a laser through the air inside the sensor. Based on the intensity and array of light beams, the monitor can determine the concentration of particles in your home. The monitor displays the current air condition of the indoor space. Some have color coding or numbering systems to indicate hazard levels.
A3: What is an air quality monitor used for?
Q3: The air quality detector can be used to detect various harmful substances such as PM2.5/HCHO/TVOC/AQI/PM1.0/PM10, and can also test indoor air quality such as humidity and temperature. If the indoor air quality is poor and there are many harmful substances, an obvious prompt will be given, and it is recommended that you start to purify the air. At the same time, many air detectors are gradually becoming more intelligent, which can be remotely observed and controlled by mobile phones, which is more convenient.
What is the safe range for formaldehyde (HCHO) and TVOC indoors?
The concentration of HCHO is less than 0.10mg/m3 and TVOC is no more than 0.60mg/m3 based on indoor air quality standards of GB/T 18883-2002 and GB 50325-2001 Class II civil construction.
What is the standard range for PM2.5?
A: Good: 0~12 μg/m³, Medium: 12~35 μg/m³, Safety value 35~70 μg/m³, Unhealthy: over 70 μg/m³.
