In many cities, they have pollution so need to verify quality. An ideal multi-function testing tool to monitor the air quality, a safeguard for family health If you worried about the air
quality around you or your children. If exceed standard, prompt alarm !

Our air quality monitor is used for various occasions:
1、This instrument is a precision instrument. When use it please avoid to contact with alcohols, perfumes and other so.fumes and other gases ,or will affect the accuracy of testing. 2、Please keep the living room, bedroom other indoor rooms closed 12 hours before you detect the air, It will he more responsive to real pollution levels. Please select the average value from different detect points,then the datas can be more accurate. 3、The instrument adopts sampling mode through the free circulation and diffusion of air, and the air quality is different when the different time it enters the detector. So it is normal that the values go up and down for the same detection point. 4、Do not blow or block the sensor detection port of instrument. This will interfere with the normal operation of the instrument. 5、The instrument is a precision instrument ,please do not disassemble the housing and internal devices by yourself.

Company Introduction
Our factory production workshop:
We are True Factory Locate in Shenzhen City China . We provide OEM ,ODM Service. Our current other models :
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);
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: What is the standard range for PM2.5?
A: Good 0~12
Medium 12~35
safe value 35~70
Unhealthy more than 70

4 Q: Why do I need to calibrate(Just HCHO and TVOC need to calibration, PM2.5 and AQI no need)?
A :Our products work in the form of outdoor formaldehyde-free air sampling as a benchmark, and then get indoor air formaldehyde
content as a comparison, so the new machine products for a long time not used, the detection of environmental temperature changes,
need to calibrated first and then tested, the value of this calibration for the subsequent detection of the accuracy of a great
relevance.Calibration environment must avoid spices,perfumes, paint, cigarettes, air fresheners,alcohol and other chemical
pollutants, so as not to damage the sensor.

5.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.

6 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.

7 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.

8 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.

9 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.
