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.
Old laser counters finally stopped. These got me back up and running at 100%. Easy to swap out.

Worked great.
The online video showing how to replace the sensors is very well done. I was able to follow it and get the new pair installed in my classic version of the sensor with no problems. Great service. Great price on these sensors. Thanks!

Useful replacement
My unit had progressively failed over the past several years. Blasting with air and suction withe vacuum eventually failed.
Ordered replacement counters and they work perfectly. Fairly easy to install given the instructional video.

replaced and working
I just replaced my old laser counters and everything seems to be working fine. The installation was easy using the video I found online. My original counters did not have the SD card, but I just ignored that part of the installation process and everything worked when I had it back outside. Easy process, not an expensive part, and we're back at it.
