BNC Connections

Hello all I purchased this kit from Robot Mesh:

http://www.robotmesh.com/df-robot/sensors/analog-ph-meter-kit

I have it up and running but I have found that this particular pH probe doesn't seem to suit my needs. I am wondering what I need to look for in the way of specifications in a new pH probe? Can I simply find any probe that utilizes a BNC connection or is there more I need to look for?

Thank you!!

I cannot resist.
If you bought a pair of shoes that didn't fit, would whatever kind of laces they had have anything to do with it?

most ph probes can be interchanged as they are simple passive devices. However you most likely have to re-calibrate when changing probes.
