So… what is the PurpleAir Zen?

I’ve heard the rumors… actually, no, I haven’t. So I came here to see, and see nothing. Yet.

Looks like I can answer my own question!


Wonder if the 6003’s in that, are more accurate than the 5003’s in the PA-II


From the comments section of this link:

the PMS6003 uses a proprietary technology-dual laser technology, which can achieve dual laser linkage and mutual calibration, thereby extending the service life more than doubled.

It won’t offer a better accuracy but longer lifetime.

If you look at the reports the answer is NO. Actually LESS accurate… On another thread I am hoping they respond to my question if something software wise was done to correct for this otherwise you have to choose, accuracy or possible durability (FYI I have had a version of the classic running for years now).
