FAQ
Q: How much range of detection of formaldehyde concentration detector,how many square meters? A: 1. The principle is less than 50m3 ,the room should be set 1 to 3 points;50 ~ 100m3 Set 3 to 5 points;More than100m3 at least 5 points. On a diagonal or plum blossom evenly distributed. 2.Sampling points should avoid the ventilation, from the wall distance greater than 0.5m. 3.The height of the sampling point: in principle, consistent with the human breathing.Relative height of 0.5m ~ 1.5m between. 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, 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. Q: Why is the PM2.5 test value changing? A: PM2.5 data are changing at all 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. Q: Why is the product sounding when working? A: PM2.5 detection need to collect a lot of mobile air, in order to ensure accurate detection of the fan needs strong operation, so a little sound is normal. Q: What is the standard for formaldehyde (HCHO)? A: ≤ 0.10mg / m3 ("indoor air quality standards" GB / T18883-2002) Q: What is the standard for total volatile organic compounds (TVOC)? A: ≤ 0.6mg / m3 (GB / T 18883-2002 and GB 50325-2001 Class II civil construction)
