There has got to be an easier way! I have a garbage UPS (cyberpower) that reports current draw via the serial port. (as do most UPS). I think I will hack into this thing.... unless somebody else wants to revers engineer it.

Dallas makes a couple 1-wire chips that monitors current & voltage: (DS2760 DS2761 DS2762) all are made for High-Precision Li+ Battery Monitoring. I would think we could use these?

I was trying to look up the PH voltage put out by the probe circuit, and I thought it's pretty low. (can't remember exactly off the top of my head).
I think interfacing the DS2762 & PH circuit for correct voltages will be the challenge.
