- How does the AQI work?
This ozone gas meter reads overall air quality index in terms of the parameters:
Laser sensor for PM2.5 to detect dust Smog (particulate matter).
Electrochemistry sensor for O3 (ozone gas).
Semiconductor sensor for TVOC (Total Volatile Organic Compounds).
Temperature and Humidity sensor.
AQI for Integrated air quality index.
Support time and date, self-calibration function.
American O3 SPEC detector 0-5ppm Low concentration ozone sensor application:
1. Air quality monitoring
2. Industrial safety
3. Air purification control
Our DM502-O3 is easy to use and maintain, and meets the requirements of industrial field safety monitoring for high reliability of the equipment. The shell is made of high-strength engineering plastic. It has high strength and good hand feel.
|Dimensions||20 × 20 × 20 cm|
Air quality index
Think of the AQI as a yardstick that runs from 0 to 500. The higher the AQI value, the greater the level of air pollution and the greater the health concern. For example, an AQI value of 50 or below represents good air quality, while an AQI value over 300 represents hazardous air quality.
DM502-O3 ozone air quality index meter features
The summation of all VOCs is called the Total Volatile Organic Compounds (TVOC). The volume of gas per classification and the sum of all gases (TVOC) are important reflections of the relevant organic compounds found in indoor air.
