Need any expert help on Conductivity sensor in a tank

I am looking for a way to measure conductivity in a tank in my greenhouse. I am wondering if anyone has any good ideas on how to make a sensor for this project.Or if there is any standard type sensor out there for this application. I am also going to control my PH in this tank as well.

But I'm not sure what to tell you about a Ph sensor, do you have any ideas so far?
