When will the Phosphate and Nitrate probe be ready ?

A nitrate and phosphate probe for the Neptune Apex would be a great invention for our Daily testers! Phosphate on the Hanna ULR can get redundant doing it every day

I don't know if they could measure it with a probe or if they'd need to use reagents.

dare to dream

Actually there are optical probes in existence that can measure nitrate among other things in real time. Since they are actual scientific measurement instruments they probably cost more than most of us could afford. Hopefully at some point in the future the technology can become scaled to the hobbyist level.
