We have received the Quantum Meters back from Apogee for recalibration. I have checked them against the one we have here are Southeast Aquariums. They all read within 8-12PAR of each other reading ~400PAR, yielding a difference of only ~2%-3%. In my opinion, this is close enough to account for human error.

Exactly what model are you using and I assume the sensor is water proof right?

Is this the ARC PAR meter? who's next in line? I think it was LorenK

who do I talk to about being put on the waiting list?

i am after Lee I think ive been on the list for atleast 4-6 months...but it was getting repaired. Another question is how long do people get to keep this thing? is it a week a month ?

I want to do a North Fulton/South Forsyth Tour of Tanks with this so those in that area stay tuned if you want to get your readings.

I have got all three specs of the 175W SE Plusrite metal halides (10k 14k 20k). I noticed your lacking data on 175W SE halide, I would love to test my bulbs, please put me on the list.
