Temtop M2000C CO2 Air Quality Monitor for PM2.5 PM10 Particles CO2 Air Pollution Detector

Item as described. Speedy delivery.

This was the perfect unit. It could easily be set up, and re-set to factory settings. The results were clear to see. The results led to a theory that air pollution is to be found in enclosed places where human carry out their modern lifestyles. Its a bit worrying to find my office needs the window opening more. Great unit, good price

Ce Temtop M2000C Moniteur de qualité de l'air, pour PM2.5 PM10 Particules CO2 Température et Humidité correspond bien à l'usage que j'escomptais. La notice est en anglais ce qui ne me gène pas.
Le chargement se fait par un cordon USB.
Le conditionnement dans une mallette métallique est aussi excellent.

for the cost this product is right on par with its functioning. I wish I could transmit the data wirelessly but its nothing a quick photo can't solve. learn how to use it and use it properly, I hope this tool lasts me several years if not more. id like some more communication options from the company to keep me updated and incorporated into their ecosystem. this product did surpass my expectations. I'm happy and glad to be more informed about the ambient air around me, take care of your health people!

It seems pretty accurate since the outdoor readings are consistent with the air quality numbers put out by Copernicus Atmospheric Service on Weather Underground.
