Best automated PO4 tester?

[Fisherman Joe]

Finally giving up on my Reef Factory smart tester.

I had a good year of it working solidly but it’s now become a random number generator when compared to the ULR Hanna checker.

I travel a bit for work, and have a full GHL setup to measure alkalinity etc, I want to be able to automate the PO4 testing.

Whats the current best PO4 automated tester please?

I'm sorry this didn't get a reply yet, but I'll give this a bump in the hopes that others will see it

If you still don't get replies, maybe repost your question in the general questions subform, I just think more members will see it there.

Good luck!

I can tell you from experience it’s not the trident NP. Bought mine in September and it’s been replaced once already. Needs replaced again. It worked for 3 tests since September. It always reads zero or .01 no matter what.
