The meter has a nice screen and a reasonably accurate dust counter. I compared it's results to the CARB air monitoring station a few blocks away and found that it usually reads 10-20 points lower up to AQI 150. At higher values it becomes less accurate often reading much lower than actual. However the main reason I bought it was to compare indoor and outdoor pollution levels to see if my air filters were working during the California wildfires and the meter works very well for that purpose.

Die Anzeige macht genau das was sie soll. Sie zeigt zuverlässig die Messwerte an. Pustet man gegen den Temperatur- und Feuchtigkeitssensor reagiert die Anzeige sofort. Die Lieferung erfolgte 7 Tage nach Bestellung. Alles bestens! Nur zu empfehlen! Der Lüfter des Gerätes ist nicht zu hören.
I would give this device 5 stars... it appears to work very well, but there are bugs in the software.... "Good" air quality is only from when the reading is greater than 0, so when the reading is zero, (no particles at all), the display goes red, and it shows "Severely Pollated" (SIC). Polluted is spelled incorrectly. A minor detail, but should be addressed, see image.
Excellent instrument for assessing air quality. Plugged it into a USB port and it immediately came to life. I'd have bought the unit with data export for a few pounds more if I'd realised it was available.
Seems to work fine, but I don't have other meter to test accuracy. RH and Temp seems in a good range. It came very well packaged inside a box with cushion foam.
ottimo, arrivato molto prima del previsto. ottimo imballo e ben custodito. lo strumento funziona benissimo ed é molto carino esteticamente. Peccato che non abbia incluso anche la data e l'ora.
works well , the quality of the screen is good it is well contrasted
Everything was fine! Same as description. Good quality product and fast delivery. thanks
nice
Very nice and good looking. Seems accurate and follow results from some online meters.
