Product description

Quality inspection
Air quality monitor test indicators: PM2.5: the main source of smog (PM1.0 and PM10 are the same); HCHO: used for formaldehyde; TVOC: mainly used for volatile organic compounds such as benzene; AQI: used for comprehensive air quality index.
The safety range of formaldehyde (HCHO) and TVOC: HCHO≤0.10mg/m3/TVOC≤0.60mg/m3/according to ("Indoor Air Quality Standard" GB/T 18883-2002 and /GB 50325-2001 Class II civil construction).
Standard range of PM2.5: good 0~12/medium 12~35/safe value 35~70/unhealthy over 70
The detection range of the formaldehyde concentration detector: the test area ≤50m3, the room should be set with 1~3 test points; 50m3≤test area ≤100m3, the room should be set with 3~5 test points; ≥100m3, the number of points should be more than 5 times. It would be better if the test points are evenly distributed on the diagonal or on the plum blossom. The height of the sampling point: in principle the same as that of human breathing. The relative height is between 0.5m and 1.5m.

Note: Our products are based on the form of outdoor formaldehyde-free air sampling, and then the content of formaldehyde in the indoor air is used as a comparison. Therefore, the new product will not be used for a long time, and the ambient temperature change needs to be calibrated and then tested. , The value of this calibration is of great significance to the accuracy of subsequent detection. The calibration environment must avoid fragrance, perfume, paint, cigarettes, air fresheners, alcohol and other chemical pollutants to avoid damage to the sensor. (Only HCH
