A part of the review has been auto-translated.
Arrived pretty fast, the whole thing. It looks nice and neatly made, complete micro-usb cable. Plugged in to the usb charging, got it all working, charging went. A few minutes later, the readings came in. It turned out that the air in the apartment is quite edible) In the package brochure with the pollution standards. If simple - then the lower left indicator shows the overall air quality - 1 is the best, 6 is best not to inhale.
assez sensible et rapide et pas trops encombrant 😃👍
Excellent tool for measuring Formaldehyde CO and CO2 and chemical pollutants. The CO2 sensor is very sensitive to any change if you exhale towards it the CO2 reading almost immediately responds to it. I'm very happy with this product and can truly recommend it.
Nice device! It arrived quickly, very well packed, just as the propaganda said ... but while in the BangGood advertising it said verbatim "Accurate detection, high precision and nice stability.", in the manual it says "This tester is a household product, the test data is only for REFERENCE, and can not used as any basic data ", I think we can then speak of misleading propaganda.
