Neptune Apex. Nitrate/Phosphate measuring

This may be a dumb question, but why haven't they come out with any device or probes to measure nitrate/phosphate.
You would think that would be very common.

I think it is an issue with reliability at price point. I saw a thread on here about a meter that does all or most, Alk, Ca, Mg, Nitrate, Phosphate but it is $1200 and $2 per test.
This one is just ad water and some type of disk.
But I agree, I would like to have it automated. I have 7 systems and 10 minutes minimum to test each one with Hanna. Over an hour.
