Calibration of PurpleAir monitors

Gino–

Yes I think the EPA conversion would be best, particularly on days of high humidity. Is there an equation including an RH factor available for the Xiaomi Mi? It would be interesting to compare the EPA and Xiaomi Mi equations.

Hi Gino–

I looked up the official website for XIAOMI (https://www.mi.com/global/ ) but could not find the air monitor that you are using. Perhaps they do not offer it any more?

Hi, sorry for the delay in responding. I was checking and Xiaomi has changed the hardware on its meters. The old meter I have measures exactly the US EPA, and the new Xiaomi hardware (partnered with Qinping) leaves much to be desired, providing a very low PM2.5 measurement.
Thank you very much for responding. My Twitter account is @ClimaPeruMundo
Best regards.
Gino.
