pH and conductivity meter?

Has anyone ever connected a pH and/or conductivity meter to an NCD transmitter? I have a specific use case that requires pH in addition to temperature and level measurement.

whats the output of the p/h sensor.

generally its 4-20mA signal.


Yes, I’m trying to ensure that the electronic module for the pH sensor will output 4-20mA. What is challenging is finding one that is also battery powered. Mostly my question is to survey the community on what others have done to obtain pH measurements…
