Apogee sq 626

[Superlightman]

Hello can the apogee sq 626 be used in a reef tank? Is he better than the 520?
Or maybe not need such an expensive meter ,would be the 420 be enough accurate for check the PAR in our tank or not?

Depends on the lighting.. Most LED only tanks wouldn't benefit until a lot of IR and/or UV diodes were added.
Wouldn't do much for t5 unless specific UV IR bulbs are used.

May help w/ MH's to get the full spectrum.
Catch though is a lot of that IR is photosynthetically inert.


Thing is the added accuracy is in a range of radiation that is somewhat questionable as to their necessity.

Now if you are monitoring UV for THC/asst flavanoids production the 626 has a lot of utility .

Keep in mind the "par" number is all inclusive so percents of each bandwidth is still not known.

(Blue sensor) Spectral Range
400 to 700 nm ± 5 nm (wavelengths where response is greater than 50 % of maximum)

(Black sensor) Spectral Range
410 to 655 nm (wavelengths where response is greater than 50 %)

(Silver sensor) The SQ-626 is an extended range photon flux density (PFD) sensor with a spectral range of 340 to 1040 nm ± 5 nm
(wavelengths where response is greater than 50 %)
I added the 50% thing. Wasn't clear at Apogee but chart tells the story.

Thank for your reply,actually I have radion 5g +t5,wich one would you recommend to me ?
