MQ-510 or SQ-520?

Pvtgloss · Nov 26, 2023

I'm going to pull the trigger on a par meter. I'm not sure if I want the 510 with the handheld device or the 520 with USB that plugs into the laptop. Does anyone have any insight on either one?
I'm leaning towards the 510.

510. My laptop cost more than the meter, I'd rather not have it near the tank while I'm digging around in the water

I just ordered the 510 and wand from premium aquatics! I'm excited. I'm a set it and forget it kinda guy so I'm not sure how much I'll actually use it once I dial my lights in.

PARwise, as this gives you more options and is software upgrade-able. The spectral graph, DLI are great features that can be beneficial, plus you can "tune" your spectrum without increasing intensity, not something you can do with a standard par meter.
