Qualified success

I managed the install and now canread the results on my computer map. Nothing but a purple dot on my iphone. No obvious way to get results. It should be visible to anyone in the world. Except me!

Hi Douglas, thank you for your feedback! Please feel free to reach out if you need any help!

PurpleAir parts & tech Support

Parts ordering online was prompt, 100% informed us, poorly packaged for shipment but arrived ok by expensive FedEx 2day ground to our residence. Installing the quality laser sensors into a PurpleAir II Classic variant Older Sensor was at best done with much difficulty for a Senior Citizen with tech experience even with a good YouTube installation video which had to be researched to find. Tech Support was outstanding but very slow to respond to my e-mail requests for assistance but very helpful after contact The rebuilt sensor was put back in service with 100% confidence on the map after restoration of the A side lockout. I want to thank the PurpleAir team for all their effort for this Volunteer location for Sacramento County Air Resources Board.
