Product Details

Smart Air Quality Detector PM2.5 gas monitor with Laser sensor High sensitivity Air detector 

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

 


 

( 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.

FAQ

 

 


 

  

Q: How much range of detection of formaldehyde concentration detector,how many square meters?
A: 
1) The principle is less than 50m3 ,the room should be set 1 to 3 points;50 ~ 100m3 Set 3 to 5 points;More than100m3 at least 5 points. On a diagonal or plum blossom evenly distributed.
2) Sampling points should avoid the ventilation, from the wall distance greater than 0.5m.
3) The height of the sampling point: in principle, consistent with the human breathing.Relative height of 0.5m ~ 1.5m between.

 

Q: Why is the product sounding when working?


A: The device need to collect a lot of mobile air, in order to ensure accurate detection of the fan needs strong operation, so a little sound is normal.

 

Q: What is the standard for formaldehyde (HCHO)?


A: ≤ 0.10mg / m3 ("indoor air quality standards" GB / T18883-2002)


Q: What is the standard for total volatile organic compounds (TVOC)?


A: ≤ 0.6mg / m3 (GB / T 18883-2002 and GB 50325-2001 Class II civil construction)
