My sensor had a bad habit of reading low (lots of zeros, but not always), but always lower than others in my area. Then Channel A started swinging between 0 and 2370. I learned how to disassemble my PA-II while troubleshooting my wild readings. (Hint: I used a small 90-degree flat screwdriver to lift "up" (out) on the plastic ring that holds everything into the sensor. Anything with a "hook" on the end that lets you pull on it would work.) When I bought the replacement laser counters, they arrived in a couple of days, and they fit exactly into my sensor. I now have reasonable matching readings. Thanks!
It was a bit difficult to install the counters on my 1.0 device with all the loose wires,
and I had problem putting it all in the cover. It's all jammed in, but works.
When I noticed my PurpleAir data showing low confidence in the readings I contacted them to inquire about possible issues. They took the time to look at the data, and concluded I had a pair of faulty sensors. They shipped new sensors to me, gave me clear instructions on how to install them, and resolved a reporting problem with the data once they were back up and running. Responses were courteous, prompt, and well thought out. They took the time to help troubleshoot the issue on their end and it led to the issue being resolved quickly. I really appreciate their dedication and it shows in such a well performing product.
Works great. Was led astray by the UI when ordering so wound up with the wrong counters. Was grateful they remedied the problem at no added cost to me = great service.
Now I have them they are working much better. Removal and installation was straightforward. Helpful staff and great + important product. Thank you!
Considerate informed service. 5 star!
