Today, I set up the hardware for the sensor array in a box, and researched for the pH meter I will need. I found two things that would work - a robust industrial sensor found at DFRobot, and a homemade solution here. I think the industrial sensor is the better option, as it does not necessitate removing the pH meter from the water at any time, and is much less likely to break. I have also run in to a theoretical problem with the EC and pH meters, however - apparently, they cannot be supplied power at the same time, according to a comment thread on the pH meter page/

I will need to research how I can replicate this solution (the links on the bottom of the thread are broken). Alternately, I may simply be able to turn the powering and ground pins off and allow a depolarization period between each reading, done in turn.
