Air Quality Detector Indoor air monitor higi Accurate Measure PM2.5 PM1.0 PM10 AQI HCHO TVOC dust meter
This product is a multifunctional air quality detector that detects 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 formaldehyde (HCHO), total volatile organic compounds (TVOC), PM2.5/1.0/10, temperature, and humidity on its digital LCD display.

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 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)
