Which do you use to measure salinity:
A hydrometer

Refractometer

Digtalmeter

I have both (Deep Six, and the digital) I get a higher reading on the Deep Six than the digital, I assume the digital is correct I calibrated it with the solution that came with, anyone know on their dependability on monitoring salinity digitally?

Pinpoint unit is suppose to be very accurate. Did you take a look at this months ReefKeeping Magazine, it has a very good article on refractometers.

Refractometer
But I monitor with a meter

Digital is not accurate. I had the one in the picture and after 1 month I could not calibrate anymore. I returned it and got the refractometer. i have had it for a year and never calibrated it once. It is always 100% spot on and I check it monthly(knock on wood).
