I'm trying to find this info anywhere, but cant seem to get an answer anywhere.
Does the PAR sensor on the Apex system give the measurements in umol/m2/s or in W/m2?

Don't quote me but if i understand your question i belive the readings are in
Micro-einsteins or µ-mol-m-2.s-1
My 2 cents i love my PAR Meter from Apex it really works great. I don't have it in my tank all the time since i use it to go thru my multiple tanks using a wand. They give a very long cable which works to reach every where i need to. And i have LED's so i don't worry about seeing the bulbs degrade actively is another reason i dont have it living in my tank all the time. But it really is a great tool.
Thanks for your reply, just used my APEX PAR meter next a conventional par meter that displays the units and can now confirm that it is indeed µ-mol-m-2.s-1
I have to say I'm not using the PAR-meter in a conventional way, nor the rest of the Aex equipement i use, but also for the purpose I currently use it for it works very well so far.
Thanks again for your reply
LED's do degrade much quicker then you think. I had to replace my Orphek Led's with new chips after 4 years as I lost so much PAR. Lots of my friends with 3-4 year old ai sols and radions have binned them due to them losing so much PAR as well... the 10year life is a myth, they may light up for 10years but are useless after much less.
