Extremely inaccurate for indoor air quality meters

Monitor displays 500 when turned on, regardless of ambient CO2 levels. Leaving it in the same place but turning it on and off gives new readings that can vary by 200-500ppm. The outdoor reading was 500, which should have been 400-425. Temperature and humidity are normal. All in all, this device was a random number generator, so I returned it. I had high hopes for this beautifully built device but it is useless for CO2 monitoring. Note. I have professional experience in measuring CO2.

Pros
  • Hands-free operation
Cons
  • Very expensive

Good for testing HCHO

If you are only interested in HCHO levels this should do the trick for you. I have used it in different environments and in different conditions it has worked well for me. At the moment it is worth 5 stars. If you want to check temperature and humidity, it is not accurate with more than 5% errors. His TVOC scale never changed under different conditions - guessing it won't work. But since I only looked at HCHO, which shows well, the errors in the other tests are negligible. That's why I give 4…

Pros
  • handy article
Cons
  • so far so good

UPDATE: Calibration fails and setpoint has shifted

UPDATE: After a few weeks of use and finding a very informative calibration, the calibration has drifted wide with outside readings around 860 (instead of 405 -430 which I received when it was new). Since I can't start the calibration mode after following the instructions, I can't fix it. It was fun while it lasted, but I encourage you to buy another one. ALT: Looks like it works by going from room to room and outside. But I can't enter the calibration mode I want to use. The instructions say…

Pros
  • Great for a small home
Cons
  • Questionable purchase for seniors
