Anything that gives  20uS  or more with a calibrated Hanna should be ok.

Can you tell us the exact model number of the Hanna Meter? I have an EC meter I use for nutrient solutions.

For CS, I rather use the same model that everyone else uses. Plus, I hope the Hanna is not as much trouble to calibrate as the one I use.
