What is anion Negatively charged particles are called negative ions. When molecules or atoms in the air lose or gain electrons, they form charged particles called ions, such as sodium ions Na+; charged atomic groups are also called "sons", such as sulfate ions. Certain molecules can also form ions under special circumstances. Negative ions, also known as negative (oxygen) ions, refer to the oxygen ions that get one or more electrons negatively charged. The main components of air are nitrogen, oxygen, carbon dioxide and water vapor. Nitrogen accounts for 78%, oxygen accounts for 21%, and carbon dioxide accounts for 0.03%. Nitrogen has no affinity for electrons, and only oxygen and carbon dioxide have affinity for electrons. However, the oxygen content is 700 times that of carbon dioxide, so most of the negative ions generated in the air are air negative oxygen ions. It is formed by the combination of free electrons with oxygen molecules in the air. Discharge (lightning) phenomena, photoelectric effects, fountains, waterfalls, etc. in nature can ionize the surrounding air to form negative oxygen ions. Air negative (oxygen) ions are negatively charged single electrons and combined with other neutral molecular groups to form negatively charged particles. Negative ions are divided into large particle size, medium particle size, and small particle size. Small particle size is beneficial to human health In general, only the study of small particle size is concerned. In natural ecosystems, forests, waterfalls and thunderstorms are important places to generate (negative) oxygen ions.

Measurement of anion content of various materials:
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.
