hydrometer dilemma

Wow I though it had been made the new standard in like the
last 5 years or so :-)

is the new scientific standard for measuring salinity"


Old Wayne, very old, as far back as the 60s :-)

I think Wayne that is mostly are fault as we may make it sound that way :-) And you will
see thing like "the new salinity std" all over the place. It was really not official until
1978......and.......about 65 years before that was when it was first proposed. Yah know,
all the cat and dog fighting took some time LOL. It use to be Chlorinity, where you
measured the chloride ion content. Hydrometers and refracts have never been the std..but
are often used. Std Sea Water Hydrometer is calibrated to 15 C . The old Std was often
called Copenhagen Sea Water, samples of real water that sat in a fault.. It is now often
called Practical Salinity Units (PSU) based on EC ( Electric Conductivity). This
conductivity std of a sea water is a sample set to a standard KCl solution of 32.43565
g/Kg @ 15 C and 1 atm.

You can buy REAL Sea Water Std here.....got money LOL

Maybe I'll just buy me a couple barrels, drive to the coast and get fresh.

You could do that but first you will still need to know what its salinity is.
