The conductivity module and probe for the neptune is straight garbage. I'm curious if those that have first hand experience with BOTH of them can tell me if GHL is an improvement.

I don't have experience with both, but i have the GHL conductivity probe. It has never once read correctly when compared to my refractometer and has continued to drift lower. I need to try calibrating it again just to see if I can get it halfway useful. So...take it for what it's worth.The conductivity module and probe for the neptune is straight garbage.
