So I noticed today while doing some testing on my salinity the following. Please note that all items here were calibrated before testing.
Conductivity/Readers
Hanna Marine Salinity meter - 33.5PPT
Apex Neptune Conductivity Probe - 33.5PPT
Pinpoint Salinity Monitor - 33.5PPT
Refractometers
BRS Manual - 35PPT
Milwaukee Digital Refractometer - 35PPT.
What do I trust!! It is off by a clear 1PPT. Which one is actually correct. I realize either number is fine but I would still like to know. Do refractometers read higher than a conductivity probe?
What gives? Any ideas?
