  • Function description

Support 2.8 "TFT LCD screen display, 320 * 240 pixels. High-speed ARM master program
Simple operation screen Using advanced laser PM2.5 detection probe, support PM2.5 detection. Using independent HCHO and TVOC air detection probe Temperature and Humidity value display HCHO testing value Exceeded alarm and Alert alarm Air Quality Index, showing the current AQI value Support rechargeable high capacity lithium battery,long time working.

When you press the multi-function button, the instrument automatically enter the boot mode. See below:

1) P M2.5 display area, showing the current PM2.5 value.
2) Formaldehyde display area, showing the current HCHO value.
3) Air Quality Index, showing the current AQI value.
4) Battery symbol, indicating battery indicator and charging indicator.
5) Temperature display area, showing current temperature.
6) Humidity display area, showing the current humidity
7) TVOC display area, showing the current TVOC value.

( Remark : When each booting up, there will be 200 seconds on screen automatic countdown. This is the formaldehyde preheating
process. HCHO and TVOC will not display real time value until 200 seconds preheating process is completed)

Formaldehyde correction method:
When the formaldehyde content is not in the normal range, the machine need to be calibrated. Correction method: Put the device into a place of good air quality ,turn it on , let it aside for 5-10 minutes,then quickly click the power button twice . you will see the HCHO value is 0.000 and TVOC value is 0.000, the calibration is completed. After correction well, go to do the next test.
What are included:
Main Unit
mini USB charging cable

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 Then Measure. If Items Are In Low Battery, The Data May Be Inaccurate

Company Introduction
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.
