    Description


    1. Built in professional duct sensor with optical IR LED sensing method. Real time monitor indoor PM2.5 concentration.

    2. Built in high accuracy temperature & RH sensor, monitor indoor air temperature & RH.

    3. Using our unique technology of compensating method, and up to nine calibration points, to guarantee G03-PM2.5 measurements accuracy in different environments.

    4. LCD displays the real time measurement and moving average value of PM2, as well as real time temperature and RH measurements.

    5. Special design six backlit LCD for six levels of PM2.5, in straight and clear read.

    6. Long-term security power supply: 5VDC with a power adaptor

    7. Option: RS485 interface with Modbus protocol

    8. Users can know very well the indoor PM2.5 concentration, and can easily select a air purifier/air cleaner. Not only see a visible effective of indoor air clean but also have a reasonable use of an air cleaning device.


    Applications


    Used in smart home to detect PM2.5 level, to make sure a good environment for human.


    How to improve air quality in your home and office


    • The first thing you need to do is monitoring your indoor air quality everyday. The monitoring information will let you evaluate the indoor air quality.

    • The G03-PM2.5 will let you know if the steps you are taking to improve your air quality are really working or not specially let you know if an $500 air purifier works any better than a $200 one. This will really help you to save money.

    • The concentration of PM2.5 probably have much difference duo to the different purpose of the rooms. The most effective way to improve indoor air quality is, detecting each room and treatment of air purification for the important rooms, such as living room and bed rooms. G03-PM2.5 supply you a real time and accurate information, it can help you to be sharp-eyed and clearheaded.

    • Please make sure the filters of indoor HVAC systems are clean, otherwise need to clean or replace filters. The unclean filter is one of sources of indoor particle pollution.

    • Please notice it’s very important for the quantity and location of air purifiers or air cleaners. Now you need the help of the real time monitor information of PM2.5 by G03-PM2.5

    Level VI

    Serious pollution

    >251

    The exercise tolerance of healthy people is reduced with noticeable symptoms, and some symptoms appear ahead of time.
