portable CO2 sensors air quality monitor test PM2.5/PM1.0/PM10 dust test equipment for car home use USA/Poland/Canada/India/Korea/Thailand
Product Description
This product is a multifunctional air quality detector that detects CO2, Formaldehyde (HCHO), Total Volatile Organic Compounds (TVOC), Particulate Matter <2.5 micron-sized particles (PM2.5/1.0/10), Temperature, and Humidity with clock and record function. As a scientific air quality detection device, it combines multiple air sensors with a built-in fan to allow real-time monitoring of CO2,formaldehyde (HCHO), total volatile organic compounds (TVOC), PM2.5/1.0/10, temperature, and humidity on its digital LCD display.

HCHO (formaldehyde) ideal range: <=0.10 mg/m³(0.08 ppm/m³)
TVOC ideal range: <= 0.6 mg/m³ (0.45 ppm/m³)
The formaldehyde alarm threshold can be set to 0.080, 0.100,0.300 or 0.600 mg/m³. If levels of HCHO exceed the setted formaldehyde alarm threshold, the device will alarm with short beeps.
Considerations
Please read the instructions carefully before using this device.
Please keep the manual handy for quick reference and troubleshooting.
Precautions
Avoid covering the air intake areas during use to avoid inaccurate measurements.
Avoid use of solvents to clean the product as residual fumes will skew air quality readings.
Avoid water or other liquids near the product to avoid electrical damage.
Do not allow unauthorized modification or repair of this product.
Certification
QA
Q: What the test index are include for air quality monitor?
A : PM2.5: is main for smog
HCHO: is for formaldehyde;
TVOC: is main for benzene,etc Volatile organic compounds;
AQI: is for Integrated air quality index.
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).
Q: What is the standard range for PM2.5?
A: Good 0~12
Medium 12~35
safe value 35~70
Unhealthy more than 70
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.
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.
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.
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.
