Matt, maybe I am missing it, but I'm not seeing anything about needing to calibrate a conductivity meter using two points.
In this article, http://www.carlosreef.com/WordPress/...arley-ph-d/#14 , he mentioned calibrating a conductivity probe, but only mentions one solution of known value.

I'm just assuming that a second calibration point can only make it more accurate. I am also assuming that the same type of slope error he talks about with the refractometer (that requires a calibration at 53mS/cm or 35 ppt) could be occurring with the conductivity probe or meter.
Maybe it's just redundant busy work, but hey, what else do I have to do?
