Underwater PAR Measurement is Strongly Impacted by 'Immersion Effect' - Reef Builders | The Reef and Marine Aquarium Blog
Apparently, with the new model, you have multiply by 1.32 to get a more accurate reading.

Thanks for sharing!!! This explains something doesn't it? Who was it (in the club) that noticed this?

Thanks for posting!! I noticed the problem back in late June when I first tested with the upgraded version. I was getting at least a 20% reduction from previous PAR readings. Bud even had me call Apogee to see if something was wrong with our PAR meter since the upgrade, but they didn't have any explanation. So good to hear that they figured out the problem - and the appropriate calculation for a corrected reading.

Thanks!

I posted a link to this thread in the Des Moines region PAR meter checkout thread. Other trustees may want to do the same.
