Very Useful.: Testing, Measuring & Inspecting

I am very satisfied with this device. It's easy to use and very useful. So I discovered noxious fumes coming from the closet, ordered airtight plastic containers for household chemicals, and improved air quality. I also found out that the old closet emits formaldehyde, I thought for a long time about throwing it away. But the old mattress I was worried about is fine. There were questions about the use of the device and the seller answered very quickly and professionally.

Pros
  • PM PARTIAL MATERIAL DETECTION -- The air pollution meter can test small particles in the room. 6-channel determination of the amount of the smallest particles (number of particles / liter) -- pm0.3 / pm0.5 / pm1.0 / pm2.5 / pm5.0 / pm10; 3-channel particle quality determination (ยตg/mยณ) -- PM1.0 / PM2.5 / PM10
Cons
  • Not as thick as others

Excellent performance!

I bought this air quality meter to get reliable evidence that I was exposed to toxic pollutants in my home. When I opened the box I was amazed that this device is small enough to fit on a window seal. Setup is very easy and the on-screen instructions on the device make it easy to understand every feature of the device. I placed the device in the corner of my bedroom because the instructions specifically state that the sensors on the device must be protected from direct sunlight. I turned on the

Pros
  • HCHO/TVOC SENSOR -- Electrochemical HCHO formaldehyde sensor, dual platinum catalytic electrode; Semiconductor TVOC sensor, indoor air quality meter can accurately measure a variety of chemical pollution, TVOC/VOC volatile organic compounds such as benzene, toluene, xylene, aromatic hydrocarbons, aldehydes, hydrogen sulfide, etc., and detect the change in molecular concentration of organic compounds. at 1000th level
Cons
  • Not bad, but...

quality product! My review after a month of use

possibility of free return. The first thing that struck me was the brightness and clarity of the screen. It's very legible and the color coding is really nice when viewed from across the room. I followed the calibration instructions carefully and it immediately alerted me to particles in the air in my apartment. I bought a new air purifier and after a short use the monitor showed that the particle level was almost zero. Luckily, this showed me that the monitor worked just as well as a brand new

Pros
  • AIR QUALITY ALERT - Desktop air quality sensor with touch button, automatic detection at start-up, 24-hour air quality curve; Comprehensive assessment of ambient air quality, US standards air quality alarm, monitor the air quality around you anytime, anywhere, to alert you to air pollution problems
Cons
  • boring packaging
