I've been trying to get my Salinity/Conductivity probe to somewhat match or close to my refractometer. But I have no luck. My refractometer is 1.026 and Apex probe is basically 1.023 (30.9). I've been using BRS ATC refractometer and calibrated it with 1.026 solution.
I've been reading all the thread on here regarding the PM2. I have my temperature probe on PM2. I set up the Temperature comp. to 2.2. Then I calibrated with apex solution 53,000. And yes, I have acclimate the solution by floating it in my sump.
Any help would be greatly appreciated.
