Salinity: Petrel vs. Predator

[Dr. Lecter]

I'm going to be using a Predator as a backup to my Petrel, and notice that the salinity setting options for each (with most current firmware for each) don't align.

The Petrel allows for "Salt", "Fresh", and what is essentially a 'hybrid'. I run the Petrel in "Salt" mode.

The Predator has a greater degree of refinement in its available salinity settings... what I want, though, is to know what setting will most closely match the Petrel's "Salt" setting.

Hi Dr. Lecter,

Fresh = 1000 kg/m^3
EN13319 = 1020 kg/m^3
Salt = 1030 kg/m^3

I want to say that normal salinity is 35 ppt so if a puter has a salt mode it would be the norm value.

Thanks much, Tyler.

....Salt = 1030 kg/m^3....

Why are you using a density of 1030 kg/m^3?

I tought 1027kg/m^3 was closer to the "average".

To be more precise, standard NOAA salt water, at 15C / 60F has a Specific Gravity of 1.026.

But of course there's no such thing as normal salt water... U can taste the difference from sea to sea!
