Why use this product:
Note:
1.Items Must Be Placed on The Indoor Static More Than An Hour Then It
Will Show The Actual Data. If Randomly Moved, The Data Will Be Inaccurate.
2.If You Can Ensure A Clean Environment, The Goods Can Be The Calibration Data, And Them Measure. If Items Are In Low Battery, The Data May Be Inaccurate.
Factor Production Line:
There are also other models for optional :
Certification
QA
1 Q: What the test index are include for air quality monitor?
A :
HCHO: is for formaldehyde;
TVOC: is main for benzene,etc Volatile organic compounds;
AQI: is for Integrated air quality index.
2. Q: What is the safe range for formaldehyde (HCHO) and TVOC?
A : HCHO≤ 0.10mg / m3
TVOC≤ 0.60mg / m3
According to ("indoor air quality standards" GB / T 18883-2002 and
GB 50325-2001 Class II civil construction).
3 Q: Why does the products make a sound when working?
A : As When the device is working , it need to collect a lot of mobile air,
the inner fan needs strong operation to ensure accurate detection.
4 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.
5 Q: which kinds of air index exceeded, would lead to Alarm sound?
A: Just HCHO data more than 0.10mg / m3, would lead to Beep sound.
