 Certification

QA

1 Q: What the test index are include for air quality monitor?
   A : PM2.5: is main for smog(PM1.0 and PM10 are the same);
      

2 Q: What is the standard range for PM2.5?
    A:   Good 0~12
           Medium 12~35
           safe value 35~70
           Unhealthy more than 70

3.Q: Why PM2.5 readings with the published value on the site is not the same?
   A : Because the location and conditions of the test is difficult to reconcile with the weather station in the city there are several sampling points, each sampling point measured data are also very different, the sampling point of the location is strictly required; height 3 to 30 meters, air circulation, can not be close to the chimney, furnace and other obvious sources of pollution. And there are no high-rise buildings, trees or other obstructions that can impede the flow of ambient air around the instrument.

4 Q: Why is the PM2.5 test value always changing?
   A : PM2.5 data are changing all the times, with the air, wind, humidity and other environmental factors change, in the room smoking, cooking fumes, car exhaust emissions, coal, chimney,furnace Such as pollution sources will change the PM2.5 value of this area, resulting in differences in the detection data.

5  Q: Why does the products make a sound when working?
    A : As PM2.5 detection need to collect a lot of mobile air,
          the inner fan needs strong operation to ensure accurate detection.
