All Plantower laser counters are pretested in PurpleAir facilities.
Replacement laser counters are intended for when a sensor’s previous laser counters fail and cannot be repaired. Make sure to select the appropriate laser counters for your device below, as each type features unique mounting and connection methods.
Installed the new laser counters and they are working fine. Installation was not difficult but the instruction video I found on YouTube was just okay. I would have appreciated a repair video link being included with the counters, preferably with a barcode.

Replacement laser counters work great
One of our original laser counters bit the dust a few months ago, so I finally got around to buying a replacement pair. It took me an hour to follow the YouTube video instructions (mostly because I kept doubting myself, not normally working with small electronics), but those instructions were complete, and I was able to install the new laser counters successfully. Within minutes after reconnecting it to power I could verify that new data was being reported, with both sensors working properly. If I have to do this again I'm sure I'll be able to do it faster next time. :-) Customer service was also good, with it getting shipped promptly after I placed the order.
