Share your experiences and ask for advice. Auto water meter

[aumwantanai]

Hello everyone.
Now I use a water meter.
1 Kamoer spa
2 Apex Trident and Np

Kamoer spa Kh/Ca/Mg/Po4 The measurements pretty much match Hanna's.
But No3 still can't find the answer. Which doesn't sit well with Hanna. hahahaha

Apex Trident and Np Kh/Ca/Mg/No3 It's equally accurate.
But Po4 is very messy as well. hahahaha

So I would like to ask you guys, which brand do you use that is accurate? please tell me
Right now I'm interested in the ReefBot Lab brand.
What do you guys think about this brand? Please tell me.

I'm just using Hanna checkers for now. They may or may not be the most accurate but as long as they're consistent, that works for me.
