Air Quality Meter
Frequently Asked Questions :
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);HCHO: is for formaldehyde;TVOC: is main for benzene,etc Volatile organic compounds;AQI: is for Integrated air quality index.
Q: What is the safe range for formaldehyde (HCHO) and TVOC?
A : HCHO≤ 0.10mg / m3TVOC≤ 0.60mg / m3According to ("indoor air quality standards" GB / T 18883-2002 andGB 50325-2001 Class II civil construction).
Q: What is the standard range for PM2.5?
A: Air Quality Index between 0-50 is considered 'good', 51-100 'satisfactory', 101-200 'moderate', 201-300 'poor', 301-400 'very poor' and 401-500 'severe'. An AQI above 500 falls in the 'severe plus' category.
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.
Q: How much range of detection of formaldehyde concentration detector, how many square meters?
A : Test area≤ 50m3, room should be set 1~3 testing points; 50m3 ≤ Test area≤ 100m3, room should be set 3~5 testing points; ≥100m3, the points should more than 5 ponits. Testing points is on a diagonal or plum blossom evenly distributed, would more better. The height of the sampling point: in principle,consistent with the human breathing. Relative height of 0.5m ~ 1.5m between.
