Whats is Included:
Q: Formaldehyde calibration method: Put the device into a place of good air quality , let it aside for 5-10 minutes, Double click the "OK" button when the device stay at interface 1 Note: The Initial values of Formaldehyde and TVOC are 1.999 and 9.999 ,the device needs manual calibration before working.
Q: Why do I need to calibrate? 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 change First calibrated 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.
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 PM2.5 test value changing? A: PM2.5 data are changing at all 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 is the product sounding when working? A: PM2.5 detection has a fan inside , it 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)
