Monitor di qualità dell'aria Temtop M10, rilevatore di qualità dell'aria per PM2.5 HCHO TVOC AQI con display in tempo reale, batteria ricaricabile

Je ne sais pas si l'appareil est bien calibré, ni s'il est précis (+ ou - 10% selon les données constructeurs, s'il est bien calibré), mais il donne des indications intéressantes de qualité d'air, avec trois paramètres de calcul : formaldéhyde, COV et particules PM2,5. On peut interroger ces trois paramètres aisément ; du coup, cela donne une idée de la qualité de l'air, de ce qui est correct ou ne l'est pas . Cet appareil au prix modeste m'a permis d'objectiver la qualité ou absence de qualité de l'air de mon logement. Selon mes critères, on est bon autour de AQI = 10 pour dormir (air quality index = index de qualité de l'air). On peut aisément avoir cet appareil dans son sac pour différents tests. Je recommande.

I originally ordered the M10 but it was out of stock so I got the M10i for no extra charge. The sensors all appear to measure what they are supposed to, when I cook food the TVOC goes up, when I shake my bed sheets the PM2.5 goes up.

Tried to use it to measure fumes from a fdm 3D printer, but the TVOC did not give any readings for PLA, even though there is a slight smell when printing so if you’re looking to measure those fumes you might need some more high end specific equipment. Haven’t tried other plastics though.

Would have been 5 stars but the description of the product says it is precalibrated, the manual says it must be calibrated. Woefully inadequate instructions for this - no idea as to temperature necessary or humidity. States outdoors but also in ventilated room. Have bought a couple and apart from that easy to use and interpret and so useful - provided I got the calibration right! Maybe I'm overthinking it. Both battery life and cable could do with being longer.

I wish the unit displayed the Good, Moderate, and Unhealthy levels with the level detected so I don't need to constantly refer to the manual.
